Flash CS3 / Flex 2 AS3 Error #1026

Posted on by

ActionScript Error #1026: Constructor functions must be instance methods.

Description:
You will get Flash / Flex Error 1026 if you have assigned the constructor of a class to be static. What you most likely wanted to do was create a static method within your class that can be called directly from the class itself rather than from an instance of the class. You are probably trying to create something like the Math.round() method within the Math class. This is a static method and can be called directly from the class.

Fix:
Remove the keyword ‘static’ from the constructor function within your class.

Bad Code:

public class MyStaticMethod
{
public static function MyStaticMethod()
{
public static function theRealStaticMethod (inputString):int

Good Code:

public class MyStaticMethod
{
public function MyStaticMethod()
{
public static function theRealStaticMethod (inputString):int

I hope that you didn’t bang your head against the wall with AS3 Error 1026. It is an simple ActionScript Error to fix with a strange description.

Flash CS3 / Flex 2 AS3 Error #1093

ActionScript Error #1093: Syntax error.

Update 2/25/2008

Description:
This is one of the least descriptive descriptions that Flash/Flex will provide you. It can be given for a number of reasons. Some that I have run into I have not found the reason for, but instead I just rewrite the entire line of code that it reports. One reason that I have found that is duplicate-able is copying code from the web and pasting it into Flash. Most especially code with quotes.

Fix 1:
Delete the line of rogue line of code and retype it from scratch.

Again I had this error and even after commenting the line of code out entirely I still received this error. Once more I deleted the code and retyped and it worked just fine. Below is the line of code commented out. Don’t beat your head on this one. Just delete and retype. I believe that this error has something to do with the copy and paste functionality within the IDE.

Bad/Good Code 1: (this code actually works after being retyped)

/*//stage.removeEventListener(Event.ENTER_FRAME, moveCar);*/

Fix 2:
Delete the quotes from the code that you copied from the web and replace them with regular quotes.

Bad Code 2:

this.thePlayer.videoSource = “main_video.flv“;

Good code 2:

this.thePlayer.videoSource = “main_video.flv”;

Fix 3:
Delete the #(pound symbol) before the color value.

Bad Code 3:

graphics.lineStyle(1, #FFFFFF);

Good code 3:

graphics.lineStyle(1, 0xFFFFFF);

Thanks to grildcheese who left a comment about Fix3 above.

Fix 4:
Do not use #include in ActionScript 3 instead use import.

Bad Code 4:

package
{
#include “myClass.as”

Bad Code 4:

package
{
import myClass;

I will continue to post reasons for AS3 error 1093 as I find them and hopefully it will help you out.

Flash CS3 / Flex AS3 Error #1086

ActionScript Error: 1086: Syntax error: expecting semicolon before mult

Description:
This is a very easy and straightforward error with a horrible description. It actually has nothing to do with a semicolon at all. All this error means is that you forgot a ‘.’ in your import before the ‘*’.

Fix:
Add the Dot

Bad Code:

import flash.events*;

Good Code:

import flash.events.*;

Hopefully the confusing description for this ActionScript Error didn’t cause you to pull your hair out.

As Always Happy Flashing

Flash Error #1086: Syntax error: expecting semicolon before dot.

Description:
Another reason for the Flex / Flash Error #1086 is because a function/method call is typed.  It is very important to type a function but do not type the call to the function.

Fix:
Remove the typing at the end of the method call.

Bad Code:

resource.readXml (requestId, onResourceXmlLoadSuccess, onResourceXmlLoadFail):void;

Good Code:

   resource.readXml (requestId, onResourceXmlLoadSuccess, onResourceXmlLoadFail);

Flash CS3 / Flex AS3 Error #1053

Posted on by

ActionScript Error #1053: Accessor types must match.

Description:
This is a great error that has absolutely no documentation. This is what Adobe has to say about it.

The non-error error. ActionScript Error #1053 from Adobe Live Docs
Notice how the right side of the image doesn’t have any text at all. It is simply left blank. To understand this error you need to understand what an ‘Accessor’ is. An ‘Accessor’ is a ‘Getter’ that accompanies a ‘Setter’. The reason it is called an ‘Accessor’ is because it accesses the variable set using a ‘Setter’.

So what does that mean for you. This error means that the Getter(Accessor) is not set as the same Type as the Setter.

Fix:
Make sure that whatever you return in the ‘Getter’ is the same ‘Type’ as what is set in the ‘Setter’.

Bad Code:

function get sClickable():String {
return _clickable.toString();
}
function set sClickable(myClickable:Boolean):void {
this._clickable=myClickable;
}

Good Code:

public function get sClickable():Boolean {
return _clickable;
}
public function set sClickable(myClickable:Boolean):void {
this._clickable=myClickable;
}

So now you know how to solve ActionScript Error #1053.

Flash/Flex AS3 Error #1023: Stack overflow occurred.

Posted on by

Error #1023: Stack overflow occurred

at MyClass/get id()

Description:
This will happen if the stack has so much data that it is full. Nothing like Thanksgiving dinner to overflow my stack.  What is a stack and how does it get full you ask. Simply put each method(function) has a stack and that stack stores data associated with the method such as local variables with the method. Although it is a good idea to understand what a stack is you really you don’t need to have an in depth understanding of stacks to understand this error and it’s solution. Basically this error is saying that you are most likely calling the function recursively. Or in other words you might be calling the function from within itself.

Solution:
To rid yourself of ActionScipt error 1023 make sure that you don’t call the method from within itself which will eliminate any type of recursion in your method call. You may be tempted to do this by setting a variable name the same as the function name. Change either one and this will go away. Notice in the ‘Bad Code1’ example that each time the getter returns what you think is an ‘int’ you actually are calling the setter function again recursively. The trace statement will also produce AS3 Error #1023

Bad Code1:

public function set id (myId:int):void
{
this._id = id;
}
public function get id ():int
{
trace(“this.id”,this.id);
return this.id;
}

Good Code1:

public function get id ():int
{
trace(“this.myId”,this.myId);
return this.myId;
}

Bad Code2:

private function recursiveLoop ():void
{
recursiveLoop ();
}

Good Code2:

private function noRecursion():void
{
someOtheFunction ();
}

Adobe actually has a reasonable explanation for this error in liveDocs. Here is a link to the Adobe page that explains ActionScript Error 1023

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

Posted on by

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

Flash CS3 / Flex Error #2136: The SWF file file:///C|/Curtism/Flash/matchWordsGameTest.swf contains invalid data

#2136: The SWF file file:///C|/Curtism/Flash/myFile.swf contains invalid data.

Fun error that you get when compiling the swf with an external AS file as your ‘Document class’. Most Likely you will get this error if you are using a document class and also have code on your timeline.

Fix :

Remove the code from your timeline or remove the Document Class

Flash/Flex AS3 Error #2007

Posted on by

Error #2007: Parameter text must be non-null.It is the error of the year Error 2007. This error is very ambiguous but is not hard to understand once you realize what it means.

This error means that you are trying to assign an object some text but you forget to target the text and instead you target the text field. In the bad example below ‘.text’ is forgotten. It is included in the Good Code

Bad Code:

for (var i:int = 0; i<15; i++) { array[i] = myText_txt;
}

Good Code:

for (var i:int = 0; i<15; i++) { array[i] = myText_txt.text;
}

And that is how you solve ActionScript Error #2007: Parameter text must be non-null.
