Cannot debug error

1

I am loading and array of images. The first image will show then I am getting an error that I cannot figure out what is causing the problem. Below is the error message and the method that is causing the error.

Thumb is the mc that I am attaching from my library. Thumb has a mc inside of that called GalleryHolder. I am then putting it into a scroller which works fine. I narrowed down the problem when I try:

thumb.GalleryHolder.addChild( target.content ); When I comment out this line, the error goes away but of course the images don’t show because its not adding.

Error:


ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
	at flash.display::Loader/unload()
	at com.ash::Main/::onImageLoaded()

AS:


private function onImageLoaded( event:Event ):void
		{
			trace( "its working" );
			
			var target:LoaderInfo = LoaderInfo( event.currentTarget );
			
			var thumb:Thumb = new Thumb();
			
			_scroller.addChild( thumb );
			
			thumb.GalleryHolder.addChild( target.content );
			
			_thumbLoader.unload();
			
			onLoaderComplete();
		}
