I've seen it before and never was able to track it down. I ended up switching to a nested Tile/Repeater instead which actually worked better for the situation anyways.

My client is seeing it quite regularly and there is no way for the application to recover from it - after clicking "dismiss" the screen remains partially drawn and no buttons work. It's all internal to Tile/Container and in a callLater() so I can't track it down to anything in my own code. The dataProvider for the tile is just a binding to an ArrayCollection. I've also tried listening for the change events manually and only setting it when I know the array has length > 0. I can reproduce this much more frequently when profiling in FB3, but my client is seeing it a lot just in normal IE plugin. The error occurs in a fairly innocent line in Tile.as (663): // Loop over the children to find the max child width and height. var n:int = numChildren; for (var i:int = 0; i < n; i++) { var child:IUIComponent = IUIComponent(getChildAt(i)); Somehow, while i goes from 0 to numChildren, it gets to be out of bounds. The full error is: RangeError: Error #2006: The supplied index is out of bounds. at flash.display::DisplayObjectContainer/getChildAt()
