Good afternoon fellow flashers!

I’ve got this rather annoying problem that I hope someone can help me with.

I’ve slightly modified a flex script from Andre Michele to run in flash. I just removed some parts from the original flex script related to the flex document information. No biggie. It runs fine. Hurrah!

The problem occurs when I try to load this particular swf (B.swf) into  
A.swf. Then, surprisingly the compiler start complaining:

[SIZE=1]TypeError: Error #1009: Cannot access a property or method of a null object reference.[/SIZE]  
[SIZE=1]at Main$iinit()[/SIZE]

It has been suggested to me that this error stems from the fact that the object has not been added to the display list. But I believe I have tried to do so after the swf has been loaded, with no luck.

Well heres the timeline script that generates the error ([COLOR=red]A.swf[/COLOR]) :

[SIZE=1]import flash.display.Loader;[/SIZE]  
[SIZE=1]import flash.display.Sprite;[/SIZE]  
[SIZE=1]import flash.events.Event;[/SIZE]  
[SIZE=1]import [flash.net](http://flash.net);[/SIZE]  
[SIZE=1]var ldr:Loader = new Loader();[/SIZE]  
[SIZE=1]var urlReq:URLRequest = new URLRequest(“B.swf”);[/SIZE]  
[SIZE=1]ldr.load(urlReq);[/SIZE]  
[SIZE=1]ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, loaded);[/SIZE]

[SIZE=1]function loaded(event:Event):void[/SIZE]  
[SIZE=1]{[/SIZE]  
[SIZE=1]trace(“LOADED”)[/SIZE]  
[SIZE=1]addChild(ldr);[/SIZE]

[SIZE=1]// also tried : addchild(ldr.content)[/SIZE]

[SIZE=1]} [/SIZE]

I’ve verified that the above script loads any other AS 3.0 based swf  
But not this one.

Below is the script from [COLOR=red]B.swf[/COLOR] in a simplified form :

[COLOR=red][COLOR=black]// [/COLOR]MAIN.AS[/COLOR]

[SIZE=1] package  
{  
import flash.display.Bitmap;  
import flash.display.BitmapData;  
import flash.display.Sprite;  
import flash.events.\*;

import flash.filters.BlurFilter;  
import flash.geom.Matrix;  
import flash.geom.Point;

public class Main extends Sprite  
{  
private var output: BitmapData;

public function Main()  
{  
output = new BitmapData( 100, 100, true, 0 );  
stage.addChild( new Bitmap( output ) );  
stage.addEventListener( MouseEvent.MOUSE\_DOWN, createExplosion );  
stage.addEventListener( Event.ENTER\_FRAME, render );  
}  
private function createExplosion( event: Event ): void  
{  
trace(“createExplosion”) ;  
}

private function render( event: Event ): void  
{  
trace(“render”)  
}  
}  
}  
[/SIZE]

Well , that’s it. I surely hope that someone can lead me to a solution to this problem.
