Hi Peter, I just tried MDLExample and see where the problem is. In UIBase method getElementAt should return null in case of JS.
var children:Array = internalChildren(); return children[index].flexjs_wrapper; When there is no children in code above flexjs_wrapper is undefined. I will try my small example and back to you.
