I've seen this problem before when a call or reference is made to a DisplayObject that isn't actually a child of the component. This is often when the DisplayObject hasn't been added to the display list using addChild() or has been removed, but is still being referenced in your code.

Check your execution order to make sure you aren't trying to reference your DisplayObject before you've added it.
