Flash CS6 / Flex Error #1009: Cannot access a property or method of a null object reference

Posted in Error, Error, errors, Flash, Flash 10, Flex at 10:06 pm by Curtis J. Morley

TypeError: Error #1009: Cannot access a property or method of a null object reference

ActionScript 3 Error #1009 is an AS3 that you can get for many anecdotal reasons. This error basically means that you are trying to reference something that isn't there yet. That something can be a variable, data from the server, or even a movieClip or other display instance. So if you try and make a call to something and are getting this error simply look at what you are trying to reference and ask yourself is it there yet.
Don't bang your head against the wall any longer. Here I explain one of the most un-obvious ways to get this error.

One reason that you will get AS3 Error #1009 is because you are trying to access a movieClip that isn't instantiated yet. For example you try and reference a movieClip named loader_mc that is inside another movieClip. you are referencing it from a class that you created. Each time you run the test the movie you get the Run-Time Error #1009. You look inside your movieClip and see that the loader_mc is right where you want it. It is on frame 10 inside your animated moveiClip. That is when it dawns on you that the call to loader_mc happens when it is instantiated. Simply, put loader_mc on frame 1 and change it's alpha to 0 and then the movieClip will be instantiated when the call from your custom class is made.

Another reason for this error is simply incorrect targeting. If you target parent.bob and the correct reference is parent.parent.bob then you will get this error as well.

Fix 1 :

Make sure the the reference is instantiated before it is called.  This means that the script is run after the object is loaded or the frame in the animation has been reached etc...

Fix 2 :

Check your targeting

Thanks and Happy Flashing

    I’m new to Flash, and I can’t quite figure out why I would be getting this 1009 error. Do you have any ideas why I might be getting the error with the following code?…

    import flash.events.EventDispatcher;
    import fl.video.*;

    thePlayer.source = “splash.flv”;

    var theCuePoint:Object = new Object();
    theCuePoint.time = 0.001;
    theCuePoint.name = “main_video”;
    thePlayer.addASCuePoint(theCuePoint);

    function splashCuePoint(evt:MetadataEvent):void {
    loadVideo();
    }

    thePlayer.addEventListener(MetadataEvent.CUE_POINT, splashCuePoint);

    function buttonClick(evt:MouseEvent):void {
    loadVideo();
    }

    theButton.addEventListener(MouseEvent.CLICK, buttonClick);

    function loadVideo():void {
    thePlayer.source = “main_video.flv”;
    thePlayer.play();
    theButton.enabled = false;
    theButton.visible = false;
    }

    Nate,

    According to your code you haven’t yet instantiated ‘thePlayer’ or ‘theButton’., unless these are on your stage. If you comment out any of the lines that start with thePlayer. you will see that the error goes away. This may be the reason for the error.

    Tell me how you have your Flash file set up so that I can help you debug a little better.

    Thanks,

    I am using an invisible button to keep my main video from downloading, found here…

    http://blog.sessions.edu/web-design/how-to-save-bandwidth-when-displaying-flash-video/

    My goal is to make a video player that acts much like the one that YouTube uses. If you click on the image, the video will load, and if you click on the play button, the video will load.

    I have an FLVPlayback component on the stage on the bottom layer, and an invisible rectangle button on the layer above, over the image portion of the FLVPlayback. The FLVPlayback is named “thePlayer”, and the invisible button is named “theButton”. The actions layer is above the other two, and each layer just has one frame.

    To get the play button to work as I want it to, I have the FLVPlayback component first load the “splash.flv” file, which is just a still image. I then used ActionScript to add a cue point 0.001 seconds into the video. When the cue point hits, it then loads the actual video.

    Error 1009 is probably the worst trash error EVER! It doesn’t tell you where the error is. It just says 1009 bla bla bla. I can take like the whole day to fix it. And it’s not because I did not know what I was doing, one moment there is no error, the next, it is there. And I never touched the code of the function that initiated the error. I was working on another part. I tried to block some codes in that function to narrow down where the error was and guess what, the error still appeared no matter what. My head is now bleeding and the wall is demolished and the error is still there.

    If you use the mxml argument -verbose-stacktraces=true the error will also output the line number where the null pointer exception was thrown. Seems to be a huge time saver for me while developing.

    i’m getting this error, because I try to access stage like this “stage.addEventListener(MouseEvent.MOUSE_MOVE, MouseListener);”, but I dont think this is right way to do, but cannot find answer anywhere. Can you help me?..

    CK,

    Great tip. Thanks for the comment.

    Josh,

    Sorry about the head trauma man. Often times commenting out code will give this error because it actually makes the value null. Be careful when commenting out code that you are not removing a value that is needed later in the code.

    Bojan,

    The syntax stage.addEventListener(MouseEvent.MOUSE_MOVE, MouseListener); is proper and will work by itself and the function MouseListener. It seems that the error is not on this line but rather somewhere else in the code. If you can give me more code I would be happy to help you out with it.

    Thanks,

    I am getting this error and can’t figure it out. If anyone can help me it would be appreciated.

    TypeError: Error #1009: Cannot access a property or method of a null object reference. at siter_fla::MainTimeline/siter_fla::frame1()

    this error pops up when I enter code. I tested the code by itself in a different flash file and it works fine, but as soon as I add it to my website that has other code in it it stops working and I get this error.

    here is the code I added

    var myloader:Loader = new Loader();

    fe1_btn.addEventListener(MouseEvent.CLICK, image1);
    function image1(event:MouseEvent):void {
    var request:URLRequest = new URLRequest(“1.gif”);
    myloader.load(request);
    addChild(myloader);
    myloader.x=486;
    myloader.y=198;

    }

    fe2_btn.addEventListener(MouseEvent.CLICK, image2);
    function image2(event:MouseEvent):void {
    var request:URLRequest = new URLRequest(“2.gif”);
    myloader.load(request);
    addChild(myloader);
    myloader.x=486;
    myloader.y=198;

    Hi, I’m new to flash and new to action scripting. I have managed in the past to get a graphic as a button go to a url when pressed. BUt now I have decided to try and use Actionscript 3.0. This was mistake number 1 as it has removed the onPress value from the code, after about half an hour I have come up with the code which seems to work once then comes up with the 1009 error.

    My code is as follows. I have also checked it for errors and it says there is none. I have also made sure that each handler has a different tag as to not get confused.

    Just for you to know each of my images/buttons are labeled as section1 and so on up to 4.

    this.section1.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler1);
    function mouseDownHandler1(event:MouseEvent):void {
    navigateToURL(new URLRequest(“http://www.mysite.com/”));
    }

    help pls

    at frame 1 i put these lines:

    ========================

    btnTest.addEventListener(
    MouseEvent.MOUSE_UP,
    function(evt:MouseEvent):void {
    gotoAndPlay(“Finish”);
    }
    );

    stop();

    ========================

    what if btnTest is on Frame5?
    what will i do to put all AScodes in single frame but then can access symbols or instance names that will load at later frames?

    I do not want to put AS codes where and exaclty the btn will appear.
    :)

    thank u

  14. Ramesh Sakibanda said,

    March 28, 2008 at 4:11 am

    Hi Matthew,

    the reason is, you might not have assigned a variable name to section1

    i.e if you included above script in a frame and that frame *should have* an Object with instance name section1

    thanks

    Hi again,

    i’m trying in timeline to create new object witch will stop scene playing until I get mouse event(that is just for lerarning, easiest way for me I think).. Here is the code from timeline..

    import vrnjci.uvod.*;

    var zaDugme = new UlaznaKlasa();

    Now, my way that I’m trying to do in constructor is to stop playing the scene, and listener for event like this..

    package com.vrnjci.uvod {
    import flash.display.*;
    import flash.display.Stage;
    import flash.events.*;

    public class UlaznaKlasa extends MovieClip{
    public function UlaznaKlasa(){
    stop();

    addEventListener(MouseEvent.MOUSE_MOVE, MouseListener);
    }

    public function Zavrsi():void{
    stage.removeEventListener(MouseEvent.MOUSE_MOVE, MouseListener);
    }

    private function MouseListener(e:Event):void{
    trace(“RADI!!!!”);
    }

    public function Main():void{

    }
    }
    }

    I haven’t found much useful examples or books online, so any help would be largely appreciated :)..

    Hi there Curtis… I am a huge fan of your site and I use it all the time, although this is my first comment. Most of the time I come to your site and I find it very helpful, usually reading your detailed descriptions of errors helps me figure out what is going on with my AS3 code… but Finally I have run into an issue which has completely stumped me! This is why I am posting on your site.

    I have been working on an AS3 version of objects in 3d space, and I have based this on Paul Ortichanian’s version of the code ( http://reflektions.com/miniml/template_permalink.asp?id=459 ) which he developed in the main timeline of an FLA. I have ported the code over to a class, but for some reason I keep getting this error, #1009, which has pretty much become my arch nemesis! Is there any way I could get you to take a quick look at my code to see if you can spot whats wrong?…it would be greatly appreciated!
    feel free to send me an email and I can send over the FLA etc.

    Thanks so much for your help and great work with the site!… you are helping build the AS3 community through your generosity!

    Hey.
    I’m getting this error only when I use this script:

    introfilmcontainer.skipknap_mc.addEventListener(MouseEvent.CLICK, skipknap);
    function skipknap(e:MouseEvent):void {

    Its only when I actually USE it. When I don’t use the button everything’s fine…
    What could be my problem?

    Working with external text in flash CS3 to create a website using external txt.

    I am using menu buttons in the main stage to change text the main external text box. Everything works fine. I added a two buttons on the sections stage to change the the text in the external text box. and i get this error:

    TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at TAQA_fla::MainTimeline/frame1()

    I have the buttons codes as:

    sections.berry_btn.addEventListener(MouseEvent.CLICK,b8Listener);
    sections.skinner_btn.addEventListener(MouseEvent.CLICK,b9Listener);

    then:

    function b8Listener(event:MouseEvent):void {
    loadFile(“berry.txt”);
    sections.gotoAndStop(“artist”);
    }

    function b9Listener(event:MouseEvent):void{
    loadFile(“skinner.txt”);
    sections.gotoAndStop(“skinner”);
    }

    Do you need to see the whole code. What do i need to get my buttons to work with out having them on the main stage.

    I am getting the 1009 error doing something a little differently from others. I have posted my question on the adobe forums, but haven’t able to get a response. I have a button click action:

    The logon function

    private function logon():void
    {
    userSession.userId = userId.text;
    userSession.password = password.text;
    var token:AsyncToken = UserSessionAssembler.createItem(userSession);
    token.operation = “CREATE”;
    }

    The userSession object is being created in the init method, and that is being called on creationComplete

    private function init():void
    {
    userSession = new UserSession();
    }

    The UserSession class is an actionscript class which I created and is mapped to a java class.

    package assets.actionscript
    {
    [Bindable]
    [RemoteClass(alias="UserSession")]
    public class UserSession
    {
    public var userId:String;
    public var password:String;
    public var status:String;

    public function UserSession()
    {
    }

    public function getStatus():String {
    return this.status;
    }

    public function setStatus(status:String):void {
    this.status = status;
    }

    public function getUserId():String
    {
    return this.userId;
    }

    public function setUserId(userId:String):void
    {
    this.userId = userId;
    }

    public function getPassword(password:String):String
    {
    return this.password;
    }

    public function setPassword(password:String):void
    {
    this.password = password;
    }
    }
    }

    If I call the create method directly in the click function I can pass the object to the java class fine and it works, but for some reason when the object userSession is passed to the create method it throws the 1009 error. I have been stuck on this for a few days and has been very frusturating trying to resolve this.

    Robert,

    I tried your code with 2 movieClips on the stage in all frames. With your code the example works fine for me. Because of this I would assume (without being able to see your whole file) that a movieClip is not on the stage or something similar.

    Actually, the second error may disappear if you resolve the first. It sounds like a movieClip is trying to be turned into a button.

    Thanks,

    Can anyone help me? I am very green at this and am just trying to do a simple, simple, simple flash site but I cannot get around this 1009 bug. It’s awful and stopping me from getting anywhere.

    Basically how do you get the program to recognize the button as not null. I guess I mean how do you get it to read the button then apply the Action script in the proper order or vice versa whcih ever is correct. I can’t believe Adobe designed this flaw into the program. Horrible! And when i say simple I mean I don’t understand hardly any of the code above. I’m really depressed over this- ruining my efforts t get a site up- i’d made such good progress til now. Any help would be sooooo appreciated.
    The code I am using is below:

    stop();

    FsAs.addEventListener(MouseEvent.CLICK, FestsAwards);
    function FestsAwards(event:MouseEvent):void {
    gotoAndPlay(4)
    }

    CsBs.addEventListener(MouseEvent.CLICK, ContsBios);
    function ContsBios(event:MouseEvent):void {
    gotoAndPlay(35)
    }

    Imgs.addEventListener(MouseEvent.CLICK, Images);
    function Images(event:MouseEvent):void {
    gotoAndPlay(61)
    }

    CstCrw.addEventListener(MouseEvent.CLICK, CastCrew);
    function CastCrew(event:MouseEvent):void {
    gotoAndPlay(111)
    }

    BlgNws.addEventListener(MouseEvent.CLICK, BlogNews);
    function BlogNews(event:MouseEvent):void {
    navigateToURL(new URLRequest(“http://www.shores.blogspot.com/”));
    }

    There are times where I’ve set up listeners in the Class Constructor for objects that live directly on the stage which works fine, but have to slightly rework the Class to add them dynamically, as the listener in the Constructor is simply beating the object to the stage – therefore returning a null. I add an init() function and place my original listeners there, and add a listener to the constructor that fires when the object is actually available:

    xPackage{

    YClass extends Whatever{

    public function YClass():void{
    addEventListener(Event.ADDED_TO_STAGE, init);
    }

    private function init():void{
    someObject.addEventListener(MouseEvent.MOUSE_DOWN, someFunction);
    }
    }
    }
    Hopes this helps some of you – it sure helped me.

    Hey,
    I like your site. It is my first stop for understanding actionscript errors.
    Regarding error 1009, I found that when loading external movie clips there is a problem with the timing of items being instantiated. A movie clip that worked fine on its own gave me this error when I loaded it into another swf.
    My solution was to start a timer and run the offending function after a second or so… not that elegant but it works.

    Here is an example of the timer:

    public function addListenersTimer():void
    {
    var myTimer:Timer = new Timer(1000, 1);
    myTimer.addEventListener(TimerEvent.TIMER_COMPLETE, addListeners);
    myTimer.start();
    }

    private function addListeners(e:TimerEvent):void
    {
    _dragger.addEventListener(MouseEvent.MOUSE_DOWN, onDraggerPress, false, 0, true);
    _dragger.addEventListener(MouseEvent.MOUSE_UP, onDraggerUp, true, 0, true);
    _dragger.stage.addEventListener(MouseEvent.MOUSE_UP, onDraggerUp, false, 0, true);
    }

    Thanks again,

    Jeff

    Jeff,

    Thanks for this great suggestion. One other thing that you can do is to listen for the COMPLETE event to fire and then assign the appropriate actions. Thanks for the compliments also. It is people like you that make writing like this worthwhile.

    Thanks and Happy Flashing,

    Hello Mr. Morley,

    I have a problem with the dreaded TypeError: Error #1009: Cannot access a property or method of a null object reference. I’m creating a flash website and I have the design layout already in flash. My movieclip buttons are not taking the playhead to the specified frame label. Here is the actionscript 3.0 code for just the portfolio movieclip button:

    main_PORTFOLIO_button.buttonMode = true;

    main_PORTFOLIO_button.addEventListener(MouseEvent.ROLL_OVER, portfolioOver);
    main_PORTFOLIO_button.addEventListener(MouseEvent.ROLL_OUT, portfolioOut);
    main_PORTFOLIO_button.addEventListener(MouseEvent.CLICK, portfolioClick);

    function portfolioOver(event:MouseEvent):void
    {
    main_PORTFOLIO_button.main_PORTFOLIO_Animation.gotoAndPlay(“over”);
    }
    function portfolioOut(event:MouseEvent):void
    {
    main_PORTFOLIO_button.main_PORTFOLIO_Animation.gotoAndPlay(“out”);
    }
    function portfolioClick(event:MouseEvent):void
    {
    trace(“Clicked”);
    gotoAndPlay(“portfolio”);
    }

    The frame label “portfolio” is on the main timeline. I want this movieclip button to go to the frame label “portfolio.” The problem comes about when I click the portfolio button to go the “portfolio” frame label. It goes to the specified frame label and outputs this error message:

    TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at Main3_fla::MainTimeline/portfolioOut()

    If you can take a look at this I would really appreciate it.

    Thanks.

    I keep on getting Error #1009 when I am on Facebook and playing Scrabble.
    I press Dismiss all and the games disappear, so I press Continue and the same thing happens! Help!

    i’m just curious, it’s an unrelated problem actually, but

    i have a button that is actionscripted to play a movieclip. the thing is, the first frame of that movieclip has a stop(); command in it.

    so my question is, will it play? which script takes higher priority? and if not, is there any way around this?

    I came across Error #1009 in a big FLA:
    I testet accesssing nested MovieClips and tell them something (e.g. gotoAndPlay). It’s no problem in my little test FLA. But in my project with long timelines, sounds and graphics, it just won’t work!!!
    The FLA is is here:
    http://www.id.uzh.ch/mels/projekte/zrm/rudi_test.fla
    If you run it, you will see the rror and it will bring you to the code I’m talking about.
    I have tried sooo many things, just nothing seems to work. Any suggestions?

    I came across Error #1009

    while trying to build a remembrance flash package.

    Essentially, I’m trying to recreate something I’ve seen on the MediaStorm website http://mediastorm.org/0024.htm a scrolling banner of images, each of which acts like a button to click through to a video player that I’ve managed to find.

    But I’ve hit a problem with the error which is driving me mad.

    The URL for the package is:

    Elksie,

    There are 2 things happening here that are giving you the error. The first is that you have a MOUSE_DOWN event that does a gotoAndStop(“Name”); and you also have a MOUSE_OUT event that changes the alpha. The MOUSE_DOWN happens while the object is still there. The MOUSE_OUT happens because you are no longer in the frame with that button.

    So the MOUSE_OUT is trying to happen on an object that is no longer accessible to Flash because it is no longer on the timeline.

    To fix this you can either just set a variable and then when you come back to the frame you can reset the alpha based off of that variable or you can change the event from a MOUSE_OUT to a MOUSE_UP like so

    profilesMC.fence.kenBettany.addEventListener(MouseEvent.MOUSE_UP, mouseUpkenBettany);

    Hope this helps and happy Flashing.

    Hello all! So, I’ve got an Error #1009 issue and would love a little guidance. On the first frame of my timeline, I have preloader animation that tracks the progress of the download. On the last frame of my timeline, I have a movie clip called INTRO_anim that loads after all of the content for my website. What I would like to be able to do is skip to the next frame of the timeline (which is where all the content is) once it’s ready and forget about playing the intro if I choose to do so. When I launch my swf and click on SKIP_btn, a bunch of 1009′s pop up along with some 1010′s. Here’s my code:

    stop();

    SKIP_btn.gotoAndStop(4);
    START_btn.gotoAndStop(2);

    SKIP_btn.buttonMode = true;
    START_btn.buttonMode = true;

    this.loaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgress);
    this.loaderInfo.addEventListener(Event.COMPLETE, onComplete);

    function onProgress (event:ProgressEvent): void {
    var loaded:Number = event.target.bytesLoaded;
    var total:Number = event.target.bytesTotal;
    var pct:Number = loaded/total;
    LOADING_anim.gotoAndStop(Math.round(pct*100));
    loaded_txt.text = “Loading Site… ” + (Math.round(pct*100)) + “%”;
    if(framesLoaded >= 22) {
    SKIP_btn.gotoAndStop(1);
    SKIP_btn.addEventListener(MouseEvent.MOUSE_DOWN, SKIP_early_down);
    SKIP_btn.addEventListener(MouseEvent.MOUSE_OVER, SKIP_early_over);
    SKIP_btn.addEventListener(MouseEvent.MOUSE_OUT, SKIP_early_out);
    loaded_txt.text = “Loading Intro…” + + (Math.round(pct*100)) + “%”;
    function SKIP_early_down (event:MouseEvent): void {
    this.loaderInfo.removeEventListener(Event.COMPLETE, onComplete);
    nextFrame();
    }
    function SKIP_early_over (event:MouseEvent): void {
    SKIP_btn.gotoAndStop(2);
    }
    function SKIP_early_out (event:MouseEvent): void {
    SKIP_btn.gotoAndStop(1);
    }
    }

    if(pct == 1) {
    loaded_txt.text = “”;
    }
    }
    function onComplete (event:Event): void {
    SKIP_btn.gotoAndStop(1);
    SKIP_btn.addEventListener(MouseEvent.MOUSE_DOWN, SKIP_down);
    SKIP_btn.addEventListener(MouseEvent.MOUSE_OVER, SKIP_over);
    SKIP_btn.addEventListener(MouseEvent.MOUSE_OUT, SKIP_out);

    function SKIP_down (event:MouseEvent): void {
    SKIP_btn.gotoAndStop(3);
    nextFrame();
    }
    function SKIP_over (event:MouseEvent): void {
    SKIP_btn.gotoAndStop(2)
    }
    function SKIP_out (event:MouseEvent): void {
    SKIP_btn.gotoAndStop(1)
    }
    }

    Any ideas? Thanks a lot for any help.

    var list:XML;
    var items:XMLList;
    var listPos:Number = 0;
    var url:URLRequest = new URLRequest( “http://www.ccchuntersville.com/new/includes/getBannerAds.php” );
    var loader:URLLoader = new URLLoader();
    loader.addEventListener( Event.COMPLETE, onLoadComplete );
    loader.load( url );

    function onLoadComplete( event:Event ):void {
    if( loader.data ) {
    list = XML( loader.data );
    items = list.item;
    }

    trace( list );
    }

    trace( list );

    The first trace works fine, but the second does not. As soon as the function is exited it seems to reset list, why? Is there some scope problem I’m just not seeing. On the next frame I’m trying to access items but I get the 1009 error.

  43. Curtis J. Morley said,

    November 3, 2008 at 3:48 pm

    Jabrat,

    I see what you mean. The second trace comes back as null. This has an easy explanation for it. If you notice the second trace is output before the first trace. This is because the second trace executes before the Event.COMPLETE triggers.

    So it is not resetting. The function is waiting for “loader” to get data where the trace that is not inside the function doesn’t wait and therefore you get the trace output before the data has arrived.

    The data is there and it is accessible in frame 2 also as long as you have waited for the “loader” to get the data first. If this the only code in frame 1 and you try and access the “items” in frame 2 then it will not have been received yet and therefore Error 1009.

    Try replacing your function with this code:

    function onLoadComplete( event:Event ):void
    {
    if ( loader.data )
    {
    list = XML( loader.data );
    items = list.item;
    nextFrame();
    }
    trace( list );
    }

    stop();

    I’m having a problem with an download progress bar I have made. All of the instance names are unique, the layers are unique, the symbols are unique. The symbol seems to referenece the classes just fine. The problem is that I get this error, after I have initialized the symbol on the stage. The next command it recieves is to toggle the visibility of the download progress bar, which it carries out, but throws this type error 1009. This would not be a problem except that it will also throw the error on the webpage with CS4.
    I’m still waiting on content for my site from my boss; however, the prototype functions except for this one Type Error.

    I figured it out. my guess, the preloader prevented the object from initializing, and by moving Download_Interface.disable(); to the frame after the preloader, made everything work. Weird…

    Hi Curtis,

    Heeelp! I’m getting the dreaded 1009! :) I’m trying to preload my main movie swf externally which has a doc class. The doc class controls a particle effect (the one we made in class) but it gives me the 1009 when it loads. If I comment out the particles “for” loop in the doc class I don’t get the error. I think it has something to do with the “stage” being passed into the ParticleLogo() function but I’m stumped. Is there a better way to do this then what I have below?

    DOC CLASS CODE:
    package
    {
    import flash.display.MovieClip;

    public class Bohmanart extends MovieClip
    {
    public function Bohmanart():void
    {
    init();

    Hi Curtis,
    I making a game in Flash CS3. I keep getting this error. Here’s the error:
    TypeError: Error #1009: Cannot access a property or method of a null object reference.at my_algebra_map_11_24_fla::MainTimeline/checkDoors()

    and here is the function checkDoors:

    function checkDoors(event:Event):void {

    var doors:Array = new Array();
    doors=[map.door1, map.door2, map.door3, map.door4];

    if(character.hitTestObject(map.door1)) {
    gotoAndStop(5);
    }

    if(character.hitTestObject(map.door2)) {
    gotoAndStop(5);
    }

    }

    I am lost as to how the code isn’t finding door1 and door2.
    Any suggestions would be great!
    thanks for the wonderful site,
    Scott

    Making a flash As3 form that takes the info entered and puts it into a mysql database by using php.

    Hello. I get this error but just if i’m dowloading the swf from a web server or I’m simulating the download in the authoring mode. I’ve got an onEnterFrame function and in the very earlier cycles it seems not able to find the .text property of a textfield wich is inside a movieclip attached from the libraryusing addChild(). I’m also sure that the addChild method is called before the onEnterFrame function starts. Any ideas? And, by the way, the error I see in my browser can be seen by anyone or just by developers? Thank you.

    Well, you can try two things…

    a) It’s better to just assign an event that fires when the new SWF is finished loading… (instead of the OnEnter way)

    ex.
    myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadCompletedFunction);

    B) And try accessing your newly loaded variables like this…

    localVar = MovieClip(myLoader.content).someVar;

    The MovieClip() wrapper apparently is required here, or things get screwed up.

    Good luck!

    Help! I’m being held hostage by error 1009!

    Here’s the problem. I have a program I’m trying to make for AIR with flash. So far, it is only a basic text editor. Here’s my code:

    import flash.filesystem.*

    stop();
    var defaultDirectory:File = File.documentsDirectory;
    var stream:FileStream;
    var currentFile:File;
    openBTN.addEventListener(MouseEvent.CLICK, openFileFunction)
    saveBTN.addEventListener(MouseEvent.CLICK, saveFileFunction)
    saveAsBTN.addEventListener(MouseEvent.CLICK, saveAsFileFunction)

    function openFileFunction(event:MouseEvent):void {
    openFile(defaultDirectory)
    }
    function openFile(root:File){
    var TXTFilter:FileFilter = new FileFilter(“Text (*.txt,*.htm,*.html)”,”*.txt;*.htm;*.html”)
    root.browseForOpen(“Open”, [TXTFilter])
    root.addEventListener(Event.SELECT, openFileSelected)
    }
    function openFileSelected(event:Event):void {
    stream = new FileStream;
    currentFile = defaultDirectory
    stream.openAsync((currentFile as File), FileMode.READ)
    stream.addEventListener(Event.COMPLETE, fileReadHandler)
    }
    function fileReadHandler(event:Event):void {
    var txt:String = stream.readUTFBytes(stream.bytesAvailable);
    stream.close();
    MainTXT.text = txt
    }
    function saveFileFunction(event:MouseEvent){
    saveFile()
    }
    function saveFile(){
    if (currentFile){
    if (stream != null){
    stream.close()
    }
    stream.open(currentFile, FileMode.WRITE);
    var txt:String = MainTXT.text
    stream.writeUTFBytes(txt)
    stream.close()
    } else {
    saveFileAs(defaultDirectory)
    }
    }
    //*******************************************************************
    //SaveAs
    function saveAsFileFunction(event:MouseEvent){
    saveFileAs(defaultDirectory)
    }
    function saveFileAs(root:File){
    root.browseForSave(“Save As”)
    root.addEventListener(Event.SELECT, saveAsFileSelected)
    }
    function saveAsFileSelected(event:Event):void{
    currentFile = defaultDirectory
    saveFile()
    }

    I have openBTN, saveBTN, and saveAsBTN on the stage. Also, it says my error is on line 41. This is inside the saveFile() function, on this line:

    stream.open(currentFile, FileMode.WRITE)

    What is wrong?

    I am doing a Flash site where buttons are clicked and external SWFs load via “addChildAt (myLoader, 0)”. Each SWF that loads has on its first frame a preloader script and movie then the main content starts at frame 2. When the site loads, it loads home.swf into eec.swf (which contains navigation). No errors yet, until I load another SWF. No matter which SWF is loaded next, I get “TypeError: Error #1009: Cannot access a property or method of a null object reference. at home_fla::MainTimeline/PL_LOADING()”. My guess is this has something to do with navigation being in the parent (eec.swf) and the function being in a child (home.swf), but I can’t figure out how to fix it without breaking the loading SWF itself. Each SWF works correctly with no error by itself. Any help would be greatly appreciated.

    Here is the eec.swf frame1 script which controls navigation:
    stop();

    import flash.display.*;

    var myLoader:Loader = new Loader();
    myLoader.load(new URLRequest(“home.swf”));
    addChildAt(myLoader, 0);

    function uiButton(event:MouseEvent):void {
    //if home button is clicked
    if (event.target==home_btn) {
    if (currentLabel==”about”) {
    gotoAndStop(“home”);
    } else {
    gotoAndStop(“home”);
    removeChild(myLoader);
    myLoader.load(new URLRequest(“home.swf”));
    addChildAt(myLoader, 0);
    }
    }
    //if New Construction button is clicked
    if (event.target==newConstr_btn) {
    if (currentLabel==”about”) {
    gotoAndStop(“home”);
    myLoader.load(new URLRequest(“newConstr.swf”));
    addChildAt(myLoader, 1);
    } else {
    removeChild(myLoader);
    myLoader.load(new URLRequest(“newConstr.swf”));
    addChildAt(myLoader, 1);
    }
    }
    //if Remodeling button is clicked
    if (event.target==remodel_btn) {
    if (currentLabel==”about”) {
    gotoAndStop(“home”);
    myLoader.load(new URLRequest(“remodel.swf”));
    addChildAt(myLoader, 1);
    } else {
    removeChild(myLoader);
    myLoader.load(new URLRequest(“remodel.swf”));
    addChildAt(myLoader, 1);
    }
    }
    //if Custom Builds button is clicked
    if (event.target==custom_btn) {
    if (currentLabel==”about”) {
    gotoAndStop(“home”);
    myLoader.load(new URLRequest(“custom.swf”));
    addChildAt(myLoader, 1);
    } else {
    removeChild(myLoader);
    myLoader.load(new URLRequest(“custom.swf”));
    addChildAt(myLoader, 1);
    }
    }
    //if About button is clicked
    if (event.target==about_btn) {
    removeChild(myLoader);
    gotoAndPlay(“about”);
    }
    }

    home_btn.addEventListener(MouseEvent.CLICK,uiButton);
    newConstr_btn.addEventListener(MouseEvent.CLICK,uiButton);
    remodel_btn.addEventListener(MouseEvent.CLICK,uiButton);
    custom_btn.addEventListener(MouseEvent.CLICK,uiButton);
    about_btn.addEventListener(MouseEvent.CLICK,uiButton);

    Here is the frame 1 preloader script that is each SWF that is loaded:
    stop();

    import flash.display.*;
    this.stop();

    this.loaderInfo.addEventListener (ProgressEvent.PROGRESS, PL_LOADING);

    function PL_LOADING(event:ProgressEvent):void {
    var pcent:Number=event.bytesLoaded/event.bytesTotal*100;
    bar_mc.scaleX=pcent/100;
    loading_txt.text=”Loading – ” +int(pcent)+”%”;

    if(pcent==100){
    this.gotoAndPlay(2);
    }
    }

    Hello Curtis J Morley,

    I still have a problem with the TypeError: Error #1009: Cannot access a property or method of a null object reference in Flash Actionscript 3. Could you please help me?

    I have several buttons,all of them on different keyframes with their own label tag (Page0, Page1, Page2, and so on). I have this code on my button in Page0 in my main time line actions layer:

    button1.addEventListener(MouseEvent.CLICK, action1);
    function action1(event:MouseEvent):void {
    //click event
    if(event.type == “click”){
    gotoAndStop(“Page1″);
    }
    }

    This button works, however: the addEventListener is not removed, it is still there when entering frame Page1! When I then try to hit button2 in frame Page1 to go to frame page2, it won’t work: the flash movie will not go to and stop at Page2, because the eventListener is still searching for button1, which is not on the stage anymore. Flash then gives me the null-object error.

    So can you please tell me how to remove the addEventListener of button1 when the button is clicked and the flash movie goes to the frame Page1?

    Thanks in advance!

    Regards, Michiel (AS3 newbie)

    If someone could help me out, I would be REALLY appreciative.

    I’ve been banging my head against the wall for TOO long on this.

    Essentially here’s how I’m set up.
    - On the mainstage I have a control layer (play and stop) that can control an intro audio
    - On the mainstage I also have a main movieclip for my menu.
    - Everything else is within this main movieclip (instance: MCmenu)

    - I’m externally loading all other pages (swf’s) via a load function, so that when the appropriate menu button is chosen, the proper swf is loaded into the viewing area designated on the stage.

    - I’ll include my main coding below, but ALL of my buttons work except one within menu_mc. and I’m still getting the following error that WON’T go away.

    TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at MrpNewMenu_fla::MCmenu_3/frame1()

    Here’s my coding for ALL of the other buttons…..

    // create a new movie clip to hold loaded content
    var contentHold:MovieClip = new MovieClip();
    addChild(contentHold);
    contentHold.x = 175;
    contentHold.y = 100;
    var swfHolder:MovieClip;

    // Loading code
    var myURLrequest:URLRequest = new URLRequest();
    var myLoader:Loader = new Loader();
    myLoader.contentLoaderInfo.addEventListener(Event.INIT, loadInitListen);

    I have no idea why this is happening and really need a solution, as I’m not that advanced in coding.

    Oh, and if it helps at all,

    the button that’s not working gives me this error whenever I try to click on it upon export

    TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at MrpNewMenu_fla::MainTimeline/menuClickListen()

    Hello Curtis,

    This has been killing me for over a week. After searching the web I landed here. This is the best explanation that I’ve seen yet. But my problem seems to be compounded. Let me try to briefly explain.

    I have a simple VR, with a scroller that moves a plane back and forth. Works good. I have Nodes that animate on the plane that call out specific information about those parts. The Nodes cannot be on all the time because the Nodes intersect. Giving false links.

    This SWF is then loaded into a main file that loads up text and video depending on the clicked Node.

    I have the Scroller on the main timeline, with the Nodes and VR inside a MovieClip. I’m stuck and was hoping to find a solution that does not include going back to AS2.

    Thanks in advance.

    i get this error when i use a code like this and go to another frame:

    addEventListener(Event.ENTER_FRAME, movingEveryFrameFunctions);

    function movingEveryFrameFunctions(event:Event):void{
    jumper();
    faller();
    movingCollisionChecker();
    mover();
    if(leftRight == 2 && allreadyIns1 == false){
    insCircle1.visible = false;
    insCircle2.visible = true;
    allreadyIns1 = true;
    }
    if(leftRight == 2 && spaceDown == true && allreadyIns2 == false){
    insCircle2.visible = false;
    insCircle3.visible = true;
    allreadyIns2 = true;
    }
    //trace(leftRight);
    }

    don’t worry all variables and such are defined elsewhere. and i figured out that the ENTER_FRAME event keeps happening and executing that function
    even while the frame is different and therefore, since the movieClips insCircle 1 through 3 don’t exist on the display list, the error comes up.

    Thanks, Curtis!

    Your example saved me hours of pulling out my hair and rewriting my (perfectly fine) code–I just put it in the wrong spot on the timeline.

    Thanks for this! I was getting the error ONLY when view the flash in Firefox. It didnt display it in the output window when I was working on it and didnt apear when using IE. Very weird. But including the MC in question through out and turning the opacity to 0% fixed it

    I have been getting this TypeError: Error #1009 for several months now at various Flash sites. It seems to happen randomly and at any site that has a lot of flash content, even simple ones like yahoo (with flash ads). It doesn’t happen on any other computer I go on, so I know it isn’t the sites. I’ve tried updating Flash, updating my browser, everything I can think of to get rid of it but just can’t seem to. I’ve done lots of forum searches, and seems that people normally experience this when working with there own Flash content, which I do not do. Any help is greatly appreciated.

    wow, thanks for the advice on this. i was getting so annoyed that i couldn’t figure it out. what i did was i made a tween on an earlier frame and instantiated a movieclip after the tween, but didn’t instantiate the movieclips on the frame before the tween when i had made the alpha to 0. thanks for the assistance!

    i, too, get the 1009 error. i’m trying to load googlemaps.swf. the code in main.swf is:

    mapBtn.addEventListener(MouseEvent.CLICK, bringMap);
    function bringMap(event:MouseEvent):void {
    var mapLoader:Loader = new Loader();
    var mapURL:URLRequest = new URLRequest(“googlemaps.swf”);
    mapLoader.load(mapURL);
    }

    googlemaps.swf pulls data from events.xml file. the load function on the is:

    var xmlLoader:URLLoader = new URLLoader();
    var eventsData:XML = new XML();

    xmlLoader.addEventListener(Event.COMPLETE, LoadXML);
    xmlLoader.load(new URLRequest(“events.xml”));

    function LoadXML(e:Event):void {
    //some more code here
    }

    the exact error on main.swf is:
    TypeError: Error #1009: Cannot access a property or method of a null object reference.

    UPDATE:

    i narrowed down my problem, and it doesn’t look its fit for this forum. it appears there’s a problems w/ Google Map’s setSize.

    i eliminated all the code in the loadXML function to the bare minimum and if i put:

    var map:Map = new Map();
    map.key = “your_api_key”;
    map.setSize(new Point(stage.stageWidth, stage.stageHeight));
    this.addChild(map);

    it WILL give me a map in googlemap.swf but WITH the 1009 error in main.swf

    if i put:

    var map:Map = new Map();
    map.key = “your_api_key”;
    map.width = 550;
    map.height = 550;
    this.addChild(map);

    it WONT give me a map but it will load OK in main.swf

    if anyone has ran into similar issue or knows a work around, i’d still appreciate some help

    Thank you.

    I’m also “new” to Flash and am making animations for our landing pages. I have not had this error before. I have made several of these. But this time one of the graphics to be clicked on is of a “coupon” that is buried in our site. Click on the graphic (set to alpha 0 as it fades in) and it takes you to the place where it is kept on the site. I “tested” the movie and at first the page comes up…followed by the error message in the OUTPUT tab. Here is the code. Please help! Thank you, Maureen.

    function gotoMASpecialsSite(event:MouseEvent):void

    var maCouponURL:URLRequest = new URLRequest(“http://www.icomamerica.com/en/promotions/marine/SummerSavings/Default.aspx”);

    Hi Curtis – thanks for the great advice on your weblog. I’m relatively new to CS4 / AS3 although I’ve been dabbling with Flash for a few years. Just a simple question wrt the original 1009 errors. Frame 1… When the AS3 is compiled at runtime along with the layers of the timeline, is there a specific order that the compilation takes place. My timeline only has one frame but 10 layers. I lay items out on the stage and give them instance names on the lower layers (bottom) and my AS3 is on the top layer. I still get 1009 errors. Does this have anything to do with the order of compilation of the layers? Thanks.

    Hi all,

    I’ve had my share on Flash with Actionscript 2.0, however getting used to Actionscript 3.0 seems to be very difficult for some reason. I keep trying to add an action to a button which is impossible.

    I’m currently working on my web-portfolio but I’m really stuck with this same error… 1009 really has me hanging by the ears…

    my code is:

    stop();

    two.stage.addEventListener(MouseEvent.CLICK, clicked);
    function clicked(event:MouseEvent):void
    {
    gotoAndPlay(“resume”);
    // This part is in case I decide to call it on another page
    //var targetURL:URLRequest = new URLRequest(“http://www.engsoc.net/~agutier2/Resume.html”);
    //navigateToURL(targetURL);
    }

    if you visit my website (www.engsoc.net/~agutier2) you can see that “two” is the ‘resume’ button… I don’t have a problem with that, it goes to the resume frame, but once I click on the button to go back (nameless button) I get the error…

    could anyone please please help?? I’d really appreciate it a lot…

    Oh sorry, I forgot to add the code for the other frame, its the following:

    stop();

    {
    gotoAndPlay(“start”);

    }
    homeBtn.stage.addEventListener(MouseEvent.CLICK, mainFrame);

    pdf.addEventListener(MouseEvent.CLICK, onMouseClick);
    function onMouseClick(event:MouseEvent):void
    {
    var targetURL:URLRequest = new URLRequest(“http://www.engsoc.net/~agutier2/images/Resume/AGutierrez.pdf”);
    navigateToURL(targetURL);
    }

    w2003.addEventListener(MouseEvent.CLICK, Clicking);
    function Clicking(event:MouseEvent):void
    {
    var targetURL:URLRequest = new URLRequest(“http://www.engsoc.net/~agutier2/images/Resume/AGutierrez.doc”);
    navigateToURL(targetURL);

    w2007.addEventListener(MouseEvent.CLICK, Clicker);
    function Clicker(event:MouseEvent):void
    {
    var targetURL:URLRequest = new URLRequest(“http://www.engsoc.net/~agutier2/images/Resume/AGutierrez.docx”);

    Hi all,

    I am new to ActionScript and Flash, and I am getting this error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at jessicaclucas_fla::MainTimeline/stopResumescroll()

    I have several different clips in one movie that have scrolling content. When I click a button to move to a different clip that doesn’t have a certain scroll, it gives me this error. I cannot figure out how to fix this. You can see the site I am working on: http://www.jessicaclucas.com. I would really appreciate some help! Thank you in advance. Here is the code:

    //Import TweenMax and the plugin for the blur filter
    import gs.TweenMax;

    //at the bottom the percentage is 1.

    //Save the old y coordinate
    oldResumeY = myResumecontent.y;

    //Calculate a new y target coordinate for the content.
    //We subtract the mask’s height from the contentHeight.
    //Otherwise the content would move too far up when we scroll down.
    //Remove the subraction to see for yourself!
    var targetY:Number = -((RESUMECONTENT_HEIGHT – RESUME_HEIGHT) * percentage) + myResume.y;

    //We only want to animate the scroll if the old y is different from the new y.
    //In our movie we animate the scroll if the difference is bigger than 5 pixels.
    if (Math.abs(oldResumeY – targetY) > 5) {

    //Tween the content to the new location.
    //Call the function ResumetweenFinished() when the tween is complete.
    TweenMax.to(myResumecontent, 0.3, {y: targetY, blurFilter:{blurX:22, blurY:22}, onComplete: ResumetweenFinished});

    I’m getting so frustrated, I’m building a photo gallery and keep getting this error. Please forgive me because I’m pretty new to AS3.

    I have 11 thumbnails at the bottom of my stage, 4 of which appear on stage at a time. Every time an instance of the RightArrow button is pressed, the functionality is intended to play a certain scene (labeled). These scenes scroll the image bar so 2 additional thumbnails are available for viewing.

    I have the exact same code (except for instance names on frame1 and frame20, and it’s working as it should.

    Frame1:
    stop();

    import flash.events.MouseEvent;

    R_Arrow1.addEventListener(MouseEvent.CLICK, RArrow1);

    function RArrow1(event:MouseEvent):void{
    gotoAndPlay(“page1″);
    }

    Frame 20:
    stop();

    R_Arrow2.addEventListener(MouseEvent.CLICK, RArrow2);

    function RArrow2(event:MouseEvent):void{
    gotoAndPlay(“page2″);
    }

    Now, when I get to frame 40, I gave the RightArrow an instance name of R_Arrow3 and this is the code:

    stop();

    R_Arrow3.addEventListener(MouseEvent.CLICK, RArrow3);

    function RArrow3(event:MouseEvent):void{
    gotoAndPlay(“page3″);
    }

    No syntax errors, but when I play the movie and try clicking the RightArrow the third time I get a compiler error of:

    “TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at wedding_gallery_fla::MainTimeline/frame40()”

    Any ideas? Thanks so much!

    Hello,

    I just came across 1009 and got puzzled at first, had no clue what was wrong. I had an .FLA with some code using a TextArea component. Yes, I did have a TextArea component in my library and yes, I was importing fl.controls.*.

    When I tried loading this SWF in another SWF, I got this error:
    TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at fl.controls::TextArea/drawLayout()
    at fl.controls::TextArea/draw()
    at fl.core::UIComponent/callLaterDispatcher()

    It’s probably obvious why I got this error, but it took me 30 minutes to figure it out: I also needed to have the TextArea component in the library of the main SWF.

    OK if anyone makes it down this far and hasen’t solved their problem, try this.

    If your refering to a button in your movie

    e.g.

    button1.addEventListener(MouseEvent.CLICK,clickon1);

    make sure that every button on the stage is labeled…

    if you have a tween make sure that both buttons are labeled

    check to make sure you don’t have a duplicate button that is not labeled

    laying underneath the button you have labeled.

    Hope this helps,

    I lost 2 nights of sleep over this. I still miss AS2

    Thanks for explaining this error in simple-to-understand terms.

    I had a straightforward animation for a website splash page that would finish with a stopped frame and two buttons would appear to allow the visitor to choose the language they would prefer.

    Running a test yielded the 1009 error. There is a stop(); action to freeze the animation and two button instances that would each call a URLRequest function. In accordance with your instructions, I simply inserted one extra frame just before the frame where the function calls adds an event listener and refers to my button instances. As long as the instances have been added to the stage before the script, no error should appear. And it worked!

    This ActionScript 3.0 stuff ain’t easy.

    I got the error with just creating a simple button which takes you to another frame… after I got fed up looking for answers I made an alpha 0% block over the area and gave it the same code… worked.

    Hi
    I was wondering if you would be able to help me.
    I Have the error coming up but I am using frame labels and there is content
    where the labels are. It is not inside of a movie. So I don’t know what to do :/

    Any help would be appreciated! Thank you!

    I am trying to simply link a URL using a button… here is the very simple code…

    blogbtn.addEventListener(MouseEvent.CLICK, onMouseClick);

    function onMouseClick(e:MouseEvent):void

    {
    var request:URLRequest = new URLRequest(“http://www.apple.com”);
    navigateToURL(request,”_blank”);

    }

    my button is named blogbtn however.. when I move to the frame where the button is located I get this output error before I even click the button. The button doesn’t work.

    TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at working1_fla::MainTimeline/frame52()
    at flash.display::MovieClip/gotoAndStop()
    at working1_fla::MainTimeline/eventResponseweb4()

    Why would it say that something not even related to the btn would be messing up?

    when I start a brand new flash file, the exact same code works perfectly so why is this code causing me so much pain? thanks.

    I, like Josh above, was about to endure some head trauma due to this issue, but you solved it for me! I had a replay button fading in. On the same frame # when the button is at 100% alpha it gets “instantiated” (what an amazing word, though I would’ve assumed the term is “instanced”) I also had the code telling the movie to gotoAndPlay frame 1. Nothing was working until I simply gave the beginning of the alpha fade the same instance name as when it gets to 100%.

    Bravo!

    Thanks so much for providing this info. I’m a self taught flash page designer and am having a real problem understanding certain aspects of AS3.0.

    AS3.0 forums (I’ve been to 4) have been pretty useless in providing me with answers thus far … cuz the answer appears to be SO simple that no one has the time to provide a helpful hint ….

    I never would have thought that I would have found the solution on a blog ….

    TypeError: Error #1009: Cannot access a property or method of a null object reference.

    Guys! What I am doing is trying to use this application located here –
    http://weblog.cahlan.com/2006/09/uploading-files-with-flex-and-php.html#links

    Basically, the app is to select multiple files from your HD and upload it to any other computer/server. As I click add it lets me browse my HD but then when I select the file gives me that error.

    If I am using this application directly then it works. As I am trying to use this app in my application where I resize it and drop it in a corner then its giving me the above mentioned error. I have not reached to a stage where I can change the code as yet.

    The code for this app is located here- http://weblog.cahlan.com/files/file_uploads/srcview/index.html

    Any help is appreciated. Thanks in advance.

    Thanks for the explanation of the mysterious Error #1009. I’m using AS3. I have a container SWF (using a document class) that loads an external SWF. It was working well and then started failing with the 1009 error. I load an XML file. When that load is complete, I use data from the XML file to load the proper SWF. Seems so simple. I’ve stripped down the container SWF’s doc class to simply the code that follows. Should also note that the external SWF runs error free on its own. If I take out the very last line that actually LOADS THE SWF … no error. It seems like the objects are added in the proper order. Maybe something with latency in loading?? Thanks for any help/insight that you can provide.

    package src.container
    {

    //import fl.controls.ProgressBar;
    import flash.display.*;
    import flash.events.*;
    import flash.geom.*;
    import flash.xml.*;
    import flash.net.*;
    import flash.utils.*;

    public class Container extends MovieClip
    {

    public function Container():void
    {

    // Loading objects for module data
    var moduleMC;
    var externalModule:MovieClip;
    var courseDataXML:XML;
    var swfLoader:Loader;
    var swfLoaderRequest:URLRequest;
    var moduleList:XMLList;

    // Load XML containing course listing
    var xmlURL:String = “data/course.xml”;
    var requestFile:URLRequest = new URLRequest(xmlURL);
    var loader:URLLoader = new URLLoader(requestFile);
    loader.addEventListener(Event.COMPLETE, xmlLoaded);

    // Function to take action after course listing XML loading is complete
    function xmlLoaded(e:Event):void
    {
    //Create load module data
    courseDataXML = new XML(e.target.data);
    moduleList = courseDataXML.module;

    // Load default module using first item’s src value
    swfLoaderRequest = new URLRequest(courseDataXML.module[0].@src);
    swfLoader = new Loader();
    addChildAt(swfLoader, 0);
    swfLoader.load(swfLoaderRequest);

    }
    }
    }
    }

    Got it. Found it here: http://www.flepstudio.org/forum/actionscript-3-0-newbies/1906-load-external-swf-error-1009-a.html

    I needed to fire an ADDED_TO_STAGE event from the external SWF. Not sure I fully understand the solution, but it is working great now.

    Used AS2 for a few years and got good at it. Did other stuff for a couple of years and came back to AS3. If Adobe is hoping to thin the Flash herd a bit, AS3 will do it. MS threw Silverlight out there to compete and be “easy”, but its just another MS bumble.

    Thanks for again for maintaining the site. It is very useful and is now in my favorites. Maybe I’ll be able to pitch-in to the support end soon.

    Hey.
    I’m new to flash and trying simply to create a link from a button on the site to another page on the site. I’ve given the button the same name and even instance name as the label on the frame I’m trying to link to. I’m getting this error when I test my movie:

    TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at index_fla::MainTimeline/frame85()
    at flash.display::MovieClip/gotoAndStop()
    at index_fla::MainTimeline/clickSection()

    This is my code:

    stop();

    recordingsdontlook_mc.addEventListener(MouseEvent.CLICK, dontlookClick);

    function dontlookClick(evtObj:MouseEvent) {
    gotoAndStop(evtObj.target.name);
    }

    Can’t figure out why this is not working….
    Could someone please help?
    Thankyou

    For the stage problem in ended up put stage into from the timeline into the class in order to get it work.

    Ex:
    public class (bla bla bla…) {
    private var $s;
    public function “class name”(s):void {
    // s is stage u put in from timeline then you use $s instead of stage inside the class
    $s = s;
    }
    }

    not the best solution.. but it works without getting errors

    Hi !
    I’m having this error 1009 on different elements, and have no idea why, to be honest… My flash project is a little dance game, using keyboard arrows… It compiles properly and all… but when I start playing/testing i get this error everytime i press the Up arrow…
    Just to mention: i created this game following a tutorial, but i decided to add a video after (but I’m no ActionScript genius… I’m still struggling everytime I deal with bits of code)

    Here’s what it says:

    “TypeError: Error #1009: Cannot access a property or method of a null object reference.

    Hey

    I keep getting this problem with my code in scene 3 (of 3 for now, planning on adding a LOT more) of my game i’m doing for a class.

    Here’s the problem code:

    stop();
    Mouse.hide();
    this.stage.addEventListener(MouseEvent.MOUSE_DOWN, shotFired);
    this.stage.addEventListener(Event.ENTER_FRAME, moveSniperScope);

    function moveSniperScope(e:Event):void {
    sniperScope_mouse.x -= (sniperScope_mouse.x – mouseX) / 3;
    sniperScope_mouse.y -= (sniperScope_mouse.y – mouseY) / 3;
    }

    function shotFired(e:MouseEvent):void {
    if (sniperScope_mouse.sniperReticle_hit.hitTestObject(targetHead)){
    targetHead.alpha = .5 /*Determine Kill Shot*/
    }
    sniperScope_mouse.y = sniperScope_mouse.y – 60 /*Gun Recoil*/
    sniperScope_mouse.x = sniperScope_mouse.x + 40
    }

    I’ve triple checked the names of my objects, etc. and they are all correct. When I debug, it finds something wrong with line 7 [ sniperScope_mouse.x -= (sniperScope_mouse.x - mouseX) / 3; ]

    any idea what it might be?

    Thanks for your time =)

    Hi everyone!

    I’ve a problem and thanks in advance for your help.

    I’ve a swf acts as a loader for another swf. Let’s name them loaderSwf.swf and targetSwf.swf respectively. the targetSwf works just fine when it’s playing as stand-alone, but when I play the loaderSwf for loading the targetSwf I get the famous TypeError 1009 at MainClass(). The MainClass() is the main document class of the targetSwf. The following is the script of the loaderSwf.

    package
    {
    import flash.net.URLRequest;
    import flash.display.Loader;
    import flash.events.Event;
    import flash.events.ProgressEvent;
    import flash.display.Sprite;

    public final class TestLoader extends Sprite
    {
    public function TestLoader()
    {
    startLoad();
    }

    private function startLoad()
    {
    var mLoader:Loader = new Loader();
    var mRequest:URLRequest = new URLRequest(“targetSwf.swf”);
    mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onCompleteHandler);
    mLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgressHandler);
    mLoader.load(mRequest);
    }

    private function onCompleteHandler(loadEvent:Event)
    {
    addChild(loadEvent.currentTarget.content);
    }

    private function onProgressHandler(mProgress:ProgressEvent)
    {
    var percent:Number = mProgress.bytesLoaded / mProgress.bytesTotal;
    //percentT.text = percent + ‘%’;
    trace(percent);
    }
    }
    }

    ——-
    Actually it’s stranger, at least logically, because the loader’s job is just loading the whole targetSwf at once not to play it sequentially! so after loading has been accomplished the targetSwf would take its place and then bear the responsibility for making each object known.

    Or perhaps I’m not logical enough in this case.

    Thanks again.

    I fixed the problem this morning…

    It was the following line in the MainClass() (the constructor).

    stage.showDefaultContextMenu = false;

    I am new to AS3.

    After pulling out my hair for about 4.5 hours with this error last night, I read this post (and the comments) and it helped me fix my file this afternoon. Thank you all for your posts, I finally feel sane again.

    I had the same problem.

    If the movie clip has a classic tween applied to it which means you have 2 keyframes. Check movieclip labels on both keyframes.

    Hope this helps.

    Hello!
    I’m getting this error 1009 “TypeError: Error #1009: Cannot access a property or method of a null object reference. at website_flashvrsn_fla::Mainpg_mc_1/stopScroll()

    I am running a simple personal site where there are several buttons that display various data. When I initiate the button that has a custom vertical scroll function, I receive the error from that point forward when any button is activated. The code is as follows:

    scrollText.text = someText;
    scrollText.multiline = true;
    scrollText.wordWrap = true;

    var bounds:Rectangle = new Rectangle(scrollMC.x, scrollMC.y, 0, 68);
    var scrolling:Boolean = false;

    function startScroll (e:Event):void {
    scrolling = true;
    scrollMC.startDrag (false,bounds);
    }

    function stopScroll (e:Event):void {
    scrolling = false;
    scrollMC.stopDrag ();
    }

    scrollMC.addEventListener (MouseEvent.MOUSE_DOWN, startScroll);
    stage.addEventListener (MouseEvent.MOUSE_UP, stopScroll);

    addEventListener (Event.ENTER_FRAME, enterHandler);

    function enterHandler (e:Event):void {
    if (scrolling == true) {
    scrollText.scrollV = Math.round(((scrollMC.y – bounds.y)/68)*scrollText.maxScrollV);
    }
    }

    The site works but I just continually receive the error once I activate the scroll. I am seeking clean code :-). Any ideas, where I may have gone wrong? I appreciate your assistance!

    I found this post to be the most helpful I’ve found so far on error #1009, but I am still wrestling the error myself!

    My AS3 (what I know of it) is very rusty, and I am relying on it to create a very simple portfolio website. I have all my main pages set up in different keyframes in a single timeline on one scene. All my main pages link perfectly through a set of six buttons. I want to have content in sub-pages linked the same way through buttons only existing on certain pages. I have the buttons set up with instances, and each time I try to write one into the code, it throws an error #1009. If I comment out that section of the code, I don’t get the error anymore. When I get the error, all my original buttons keep working- business as usual- but the new button refuses to work.

    Any thoughts? Here’s a sample of my code:

    stop();

    //Plays through to next page
    function goHome(event:MouseEvent):void
    {
    gotoAndStop(1);
    }

    //Sets the event listener for the about button
    home_btn.addEventListener(MouseEvent.CLICK, goHome);

    //Plays through to next page
    function goAbout(event:MouseEvent):void
    {
    gotoAndStop(20);
    }

    //Sets the event listener for the about button
    abt_btn.addEventListener(MouseEvent.CLICK, goAbout);

    //Plays through to next page
    function goPort(event:MouseEvent):void
    {
    gotoAndPlay(40);
    }

    //Sets the event listener for the about button
    port_btn.addEventListener(MouseEvent.CLICK, goPort);

    //Sets the event listener for the resume button
    res_btn.addEventListener(MouseEvent.CLICK, goRes);

    //Plays through to next page
    function goRes(event:MouseEvent):void
    {
    gotoAndPlay(71);
    }

    //Sets the event listener for the contact button
    con_btn.addEventListener(MouseEvent.CLICK, goCon);

    //Plays through to next page
    function goCon(event:MouseEvent):void
    {
    gotoAndStop(90);
    }

    //Sets the event listener for the scoop button
    scoop_btn.addEventListener(MouseEvent.CLICK, goScoop);

    //Plays through to next page
    function goScoop(event:MouseEvent):void
    {
    gotoAndStop(110);
    }

    //Sets the event listener for the fonts button
    //fonts_btn.addEventListener(MouseEvent.CLICK, goFonts);

    //Plays through to next page
    //function goFonts(event:MouseEvent):void
    //{
    // gotoAndPlay(130);
    //}

    The commented code at the end is what throws the error if I un-comment it.

    Any help would be sincerely appreciated!

    I’m having a problem making a DVD Menu type thing. Basically, I have on the first frame the menu set up. When you click a button on the first frame, the code is supposed to take you to the second frame where it has the flvplayback and buttons on the bottom to return to the previous frame or navigate within the movie file. The second frame only controls previous cue point and next cue point. The problem I have is that I get the 1009 error code when test it. The code tells me, after debugging, that it’s on something in the first frame. After reading this thread, I looked as hard as I could. Below is my code. Can anyone help?

    I fixed my problem… my frame1 for my main stuff was blank, because I thought I’d just have the loader. But then I simple put my main stuff under the loader – so it’s in all frames! The loader ends at frame1, but the main stuff goes from frame1 to frame2!

    MAKE SURE YOUR MAINSTUFF IS ON FRAME1 ALSO!!!!

    RakShith – I apologize that the code was cut off. Your “while” statement is where it looks incomplete. Try using the “code” button on the comments before pasting.

    I am a complete newb when it comes to flash and actionscript 3. I have set up a button class and document class. In the button class I have code that defines what the text on the button will be. In the document class I have code that defines what the text on the instances of the button will be. I keep getting the error TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at siteButton/setLabel()
    at Website()

    This is my button class code (siteButton)
    package
    {

    import flash.display.SimpleButton;

    public class siteButton extends SimpleButton
    {

    public function siteButton()
    {
    trace(“siteButton has been cerated”)
    }
    public function setLabel(newLabel:String):void
    {
    this.buttonLabel.text = newLabel;
    }
    }
    }
    This is my document class code (Website)
    package
    {

    import flash.display.MovieClip;

    public class Website extends MovieClip
    {

    public function Website()
    {
    skipButton.setLabel(“Skip”);

    }

    }

    }
    I’m guessing that it’s trying to execute the function before it knows what it is. I just don’t know how to solve it.

    after modifying an actionscript tutorial I found online to create an oop quiz application, this is the code, and I cannot figure out what the problem is :

    Hi Curtis,

    Your error explanations are actually made for humans to understand. I can’t thank you enough. I just read your post about the underlying reason why I’m running into error #1009, “Trying to reference something that isn’t there yet”. While, I do understand the reasoning behind the error, I don’t know how to solve the error in my situation.

    I have a master container that I load my sections into. Each section, or swf has “intro” & “outro” states so the transitions are smooth. I have this working properly with no issues.

    I’ve decided to add an XML gallery as another section, which has a corresponding Gallery.as file. I have it working properly on its own. However, if I add it to the master container, and run the movie, I get this:

    TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at Gallery()
    TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at Gallery/urlLoadComplete()
    at flash.events::EventDispatcher/dispatchEventFunction()
    at flash.events::EventDispatcher/dispatchEvent()
    at flash.net::URLLoader/onComplete()

    Mind you, all movieclips and actions are on the first frame of my gallery.swf.

    Looks like this all has to do with the Gallery.as file. I’m wondering if this is a targeting/scope issue? Or, does my master container not realize the gallery.swf exists? According to your comments about the 1009 error, the movieclip isn’t instantiated yet. Not sure where to begin in this situation. The other sections work, why not this one? If you could at least point me in the right direction that would be fantastic. Any help would be greatly appreciated.

    If what I’m describing doesn’t make much sense, I could post my files.

    Hi, What about this error displaying when accessing an empty table from a local sql database?

    var selectStmt:SQLStatement = new SQLStatement;
    selectStmt.sqlConnection = conn;

    selectStmt.text = “SELECT * FROM Guest ORDER BY entryID DESC”;
    selectStmt.execute();

    var result:SQLResult = selectStmt.getResult();

    The Guest table in this case is empty though no rows returned. If the table has more than one row, then the error doesn’t show up. Any other ways to check a database table if it’s empty or not without getting an error?

    thank you
