Actionscript 3 :: Extended Classes Doesn't Understand Updates?
Dec 2, 2011
I use Flash Professional CS5.5 with Gaia FrameWork in my project. movieclips in the project have extended classes and the problem is that when I give new functionality to my classes they doesn't work in an build project. for example function s cann't be found, trace doesn't work and so on. All the old functionality works. When I change class name then it works fine. but then it happens again. I made new project and coped all the content, but still it happens. I event rainstalled flash but nothing works.

The examples I'll use don't do anything - they're classes without ANY members - no variables, methods, anything.
Let's say I extends Sprite and call it MySprite.
I save it in test.core
[code]...
Now I create another custom class called MyWindow that extends MySprite.
I save it in test.windows
[code]...
Then I create another class that extends MyWindows (the example I'll use is a document class - but that doesn't matter - I've tested using an instance too).
[code]...
Notice that I'm not even trying to instantiate the helper classes - just having them there throws the error.
If there is only a single helper class, everything runs fine.
Also note that - as far as I can tell - this only happens when extending one class from another package, then extending that class with more than one helper object.I'm pretty sure there's no namespace bumps or typographical errors, as this is a very pared-down version of the original application.
EDIT: seems the problem exists even without the crossing packages - even extending MySprite in the document class with multiple internal classes generates this error.

I have this problem from time to time with AS3 where I extend a Class and then try call methods and variables which are public from the new class but I get errors that method or variable doesn't exist. My IDE recognises the methods and variables though.[code]When I run the script flash hates it. I thought when you extend a class it was supposed to inherit its properties and methods?Does anyone else have these problems? I shouldn't have to cast it as Box. I swear I have this working in a project but cant see the different in setup?

I'm developing an AS3 application which has some memory leaks I can't find, so I'd like to ask some newbie questions about memory management.Imagine I have a class named BaseClass, and some classes that extend this one, such as ClassA, ClassB, etc.I declare a variable:
myBaseClass:BaseClass = new ClassA();
After a while, I use it to instantiate a new object:
myBaseClass = new ClassB(); some time after
myBaseClass = new ClassC();
and the same thing keeps happening every x millis, triggered by a timer.Is there any memory problem here? Are the unused instances correctly deleted by the garbage collector?

Im building a project using an MVC pattern. I have (pseudo) abstract classes Model and View, each extended with particular models and views. But I cannot access properties on the extended classes of Model...Model simply distributes XML data, heres its constructor:
Code:
public function Model(data:XML)
{
_data = data; /*_data is a protected var of type XML in Model*/
}
MainModel extends Model, and has a property called _background of type Background which also extends Model:
Code:
private var _background:Background = new Background(some XML source);
public function MainModel(data:XML)
{
[code]....
The problem arises when I try to pass MainModel's background property as a parameter of _bgView (highlighted in red above). The compiler says there is no background property on Model, which is true, but I need it to look at its extended class MainModel, not Model. I've typed MainView's constructor parameter with MainModel, but it is still seeing it as Model.

I have created a simple method to retrieve XML output from an HTTPService and populate a database from it, but due to the async nature of Flex, the functions go through while its still retrieving data - hence causing the function to return a null value. find code below;
View: Declarations
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:dao="database.*"
[Code]....
But it can go through the database population before it can retrieve the result from HTTPService hence producing a null result.

If I have a class that extends another, e.g.,
package {
import flash.display.Sprite;
public class MySprite extends Sprite{
[Code]....
and extend that class, if more than one internal classes are defined:
package {
public class MainClass extends MySprite {
public function MainClass():void{}
[Code]....
ReferenceError: Error #1065: Variable MainClass is not defined.Note that this only happens (as far as I can tell) when the public class of the package extends another class, and multiple internal classes are defined. The internal classes don't even need to be instanced or referenced to generate the error (the bare-bones code above will error out). If only a single internal class is defined, it works fine (no error). Even if the internal class is instanced.

I have created a few Event and Command classes for use in my Cairngorm projects.For example, I created an class that extends URL... that allows me to set callback functions upon completion or failure of the corresponding Command. To accomplish this, I also had to create a new Class that implements com.adobe.cairngorm.commands.ICommand that I extend for all Commands in my projects.Now, I want to use these two classes across all of my Cairngorm applications. What is the best way to do this? Should I just edit the Cairngorm source for CairngormEvent and ICommandand recompile the Cairngorm MVC (is that even possible)? Or add my two classes to the Cairngorm source and recompile the Cairngorm MVC? Or should I just add them to a shared library?I've chose the third option for now, but this requires that I reference the Cairngorm library in both my library and each project. I am wondering if there is a better practice and what the benefits are.

Let's say Class A has the flash.events.Event imported. Now let's say Class B extends Class A. Why in the hell do i need to import flash.events.Event in Class B? It makes no sens at all to me.

I am working with a flex project with a main mxml file and two actionscript classes that draw graphics. From reading tons of articles and posts I discovered that they must extend UIComponent, which they do. The first actionscript class draws the image fine. The first class then makes the call to create a new object. The second object does not display. In the pure actionscript version I had to pass the stage as a reference for the second class to draw.
I also found a similar question here at stackoverflow:UIComponent extended class isn't showing UIComponent extended class. But I was not sure how to apply it to my example.Which, if any UIComponent methods should be overrided for the second object to display? How specifically should I implement them in this example?
// First class "Ball" draws a circle successfully then creates a second object "MyRect"
package dr {
import flash.display.*;
import flash.display.Sprite;

Code:
var tr:fo = new fo();
Now when i run this swf ... it traces nothing ... ?( The as file is named fo.as and is in the same foledr as the swf file )

I was asked to update some information on a certain project. The weird thing is that whenever I try to export the movie from Flash (I work with CS3 Professional), I get errors. Before even changing anything. All of them are reporting MovieClip not being recognized ("The class...... must subclass flash.display.MovieClip since it is linked to a library symbol of that type" (and a few SimpleButtons too). There is a total of 57 errors. All the classes import and extend MovieClip.
Now I'm pretty sure this doesn't have anything to do with the code itself, since this project was already published and tested working as it is. I tried adding Class paths in the preferences menu but this didn't seem to help.

I have 1 class (that is extending a UIcomponent) that is representing a component. In that component I create different instances of another class that is also a UIComponent but this class doesn't show up in de first class. I see that it is running and that it has the correct hights but I got the feeling that it doesn't show up with this hights. If I trace I see the width and height is 200 X 200 but there is still nothing visible in my component.

Problem is that i want to catch messageClientDestroyed and send to that destination a message that the user has disconnected.But blazeds destroys messageClient when you add a subtopic.So how to understand that if session is invalidated and all messageClient are being destroyed or the user just enter another place and add a subtopic to his consumer. I'am also open for other solutions to implement that mechanism.When user disconnected by session timeout or closed the site browser etc. i wanna catch it and send a message to subscribed destinations.

In this file are the following files - and includes the .swf file compiled from the Flex project.[code]The context root of my application is the same as the artifact ID of the WAR, so it is FALCON-WAR.When I launch mvn jetty:run, I get the following print to the console:However when I try to navigate to URL...on my browser, I get the following, when I expect to launch the .swf file from the web.xml definition.

I am trying to understand the method transition that falls in the Matrix Class. I am using it to copy pieces of a bitMapData. But I need to better understand what transitions do. I have a tilesheet that has 3 images on it. all 30x30 pixels. the width of the total bitmap is 90pxs. The first tile is green, the second is brown, and the third is yellow. If I move over 30pxs using the matrix that transitions, instead of getting brown, I get yellow, if I move over 60px, I get brown. If I move -30 pixels, then the order is correct. I am confused on what is going on.
