Clearing List Control

[Matthew Weir]

I'm stumped guys.  I must be missing something completely, ridiculously, easy.
list.selectedIndices = new Vector.<int>();
                var ac:ArrayCollection = list.dataProvider as ArrayCollection;
                list.dataProvider = null;
                ac.refresh();
                list.selectedIndices = null;
                list.selectedIndex = -1;
                list.dataProvider = ac;
                list.invalidateDisplayList();
                list.validateNow()
Still shows selected items.
Help!  Please :)
