Flex 2/ Flash CS3 Warning / Error #3590: String used where a Boolean value was expected. The expression will be type coerced to Boolean.

or

Warning: 3590: int used where a Boolean value was expected. The expression will be type coerced to Boolean.

Description:
This is a ActionScript error is more of a warning than a true AS3 error. It will be displayed in strict mode and simply means that you have quotes around your Boolean value. Even though you may get this AS3 error it won’t prevent Flex or Flash from compiling nor ActinoScript code. It will convert it for you though. Thanks Flash for doing that for us.

AS3 Warning #3590 Fix 1:
Make sure that your boolean (true or false is not inside quotes).

Bad Code 1:

myObject.visible = “false”;

Good Code 1:

myObject.visible = false;

AS3 Warning #3590 Fix 2:
ActionScript 3 uses true and False rather than 0 and 1 for boolean. Although it does allow 0 to make it through without giving this error.

Bad Code 2:

myObject.visible = 1;

Good Code 2:

myObject.visible = true;

AS3 Warning 3590: Fix #3 – *Warning* This method will solve the problem temporarily and allow you to publish your code BUT it will cause you many headaches later. You will not get any warnings or error messages and this is a bad thing I Promise! If you are going to proceed down this path make sure to recheck these boxes after you are done publishing your one problem movie. With that much said, The way you do this is to turn off Strict (Verbose) Error Messages in your preferences as shown below.

Go to File >> Publish Settings >> Click on the “Flash” tab >> Next to “ActionScript version:” click the “Settings…”

AS3 Error 1118 -Implicit Coercion

AS3 Warning 3590 Fix #4 – In the example below you will see that the function “Return Type” is listed as Boolean when it needs to be listed as String.  To fix this simply change the Return Type to String or return a Boolean value “true” or “false”.

Bad Code:

function bob():Boolean
{
return “message”;
}

Good Code:

function bob():String
{
return “message”;
}

AS3 Warning 3590 is pretty easy and straight forward.

As always – Happy Flashing

Flex 2 / Flash CS3 Syntax Error #1100

Posted on by

Error #1100: Syntax error: XML does not have matching begin and end tags.

Description:
Here is another easy AS3 error. This Flex/Flash Error means that your XML is not valid because the end tag is simply missing or you left off the end slash (/). *Note: This AS3 error is similar to ActionScript Error #1085

Solution:
Close that end tag.

Bad Code 1

var dogXML:XML =
<dog>
<name>Fido
</dog>

or

var dogXML:XML = new XML();
dogXML =
<dog>
<name>Fido<name>
</dog>

Good Code

var dogXML:XML = new XML();
dogXML =
<dog>
<name>Fido</name>
</dog>

I hope this helps you solve ActionScript Error #1100

As Always Happy Flashing

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 2 AS3 Warning: #3596: Duplicate variable definition.

Posted on by

Warning: 3596: Duplicate variable definition.

Problem:
You are using the same variable and Flex/Flash doesn’t like it.
Fix:
Change the name of one instance or unnest your loop.

Bad Code:

var myArray1:Array = [“a”,”b”,”c”,”d”,”e”];
var myArray2:Array = [myArray1];

//This first loop goes through the parent array
for (var i:int=0; i < myArray2.length; i++)
{
//this second loop iterates through the nested array
for (var i:int=0; i < myArray1.length; i++)
{
trace(myArray2[i][i]);
}
}

Good Code:

var myArray1:Array = [“a”,”b”,”c”,”d”,”e”];
var myArray2:Array = [myArray1];

//This first loop goes through the parent array
for (var i:int=0; i < myArray2.length; i++)
{
//this second loop iterates through the nested array
for (var j:int=0; j < myArray1.length; j++)
{
trace(myArray2[i][j]);
}
}

or

var keys:String = “Word”;
for (var i:int=0; i < keys.length; i++)
{
//Code
}

for (i=0; i < keys.length; i++){
//More Code
}
