Normally you do not put display objects in the array collection, just data, then the renderer creates the display object to display the data.

Here's a brief description: ModelLocator has an -Album has --Photos, an ArrayCollection of ---Photo, has a ----thumbnailLoader, a loader that contains a -----Bitmap There is a list of galleries, and upon selecting one, the album is populated with photos and a viewstate containing this TileList is set to current: <mx:TileList id="thumbTile" dataProvider="{model.album.photos}" change="switchPhoto(thumbTile.selectedIndex)"> <mx:itemRenderer> <mx:Component> <mx:Image source="{data.thumbnailLoader.content}"/> <!--the problem is here --> </mx:Component> </mx:itemRenderer> </mx:TileList> On loading the first album, everything works just fine. After going back to the initial viewstate, clearing the ArrayCollection, and repopulating it, I get an error when switching the viewstate to show another album (or the same one a second time): ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. at flash.display::DisplayObjectContainer/removeChild() (I don't recognize any of the code in the call stack, and make no calls to removeChild() myself) If I remove the binding in the itemRenderer, the rest of the app works but there are no longer thumbnails in my tilelist. Does this sound familiar to anybody? I realize it's a little vague without more code, but there's a lot of it and I'm a beginner so I want to test the waters first... Thanks!
