So my final solution to this problem is to copy ArrayCollection and
ListCollectionView and rebrand those as my own and update the private
handlePropertyChangeEvents method. Fortunately all interfaces seem to be
consistently implemented and my ADG behaves likes before. Added this:
enablePostSortReorder
private function handlePropertyChangeEvents(events:Array):void
{
var eventItems:Array = events;
if (sort && enablePostSortReorder || filterFunction != null)
