[flexcoders] addChild doesn't effect for some reason REFdn2065133102

[dennis]

In small test application I have the follow object. stack

 

The "Main.mxml" loads the  EntryClass.as ->  "class EntryClass" (that
doesn't extends anything)  -> "public static function Main()".

 

This EntryClass.Main() function is doing the follow:

 

      var mxmlApp:Application = Application(Application.application);

      var mainAppClass:MainAppClass=new MainAppClass();

      mxmlApp.addChild(mainAppClass);

      

So the mainAppClass is loaded.

Now the MainAppClass extends the UIComponent and in its constructor does
this:

 

      var buttonFromMainClass:Button=new Button();

 
buttonFromMainClass.x=20;buttonFromMainClass.y=20;buttonFromMainClass.label=
"hello world";

 

to add it to stage I call

 

      addChild(buttonFromMainClass);

 

and here is the problem! The button is not appeared on the stage, but using
this code:

 

      Application(Application.application).addChild(buttonFromMainClass);

 

the button is added to the stage and it is visible.

 

Why the button is not added to the stage with the simple addChild? Where am
I wrong?

 

Something that might be help, in EntryClass.Main() if I create a button and
add it with the mxmlApp.addChild the button is added and appeared on the
stage normally, so there is no problem with the use of mxmlApp.addChild.

 

Best regards
