Description

Steps to reproduce:
1. Run code below

Actual Results:
list2 and list3 reports a length of 1 after the filter input has changed

Expected Results:
list3 and list3 should report a length of 0

Workaround (if any):
Don't know, maybe subclass ListCollectionView..? Wouldn't be the first class I have to subclass to fix a bug myself.

-------------

var numberToMatch:Number = 1;

var list1:ArrayCollection = new ArrayCollection([1,2,3]);
list1.addEventListener(CollectionEvent.COLLECTION_CHANGE, function(event:Event):void

{ trace(event); }

);

var list2:ListCollectionView = new ListCollectionView(list1);
list2.filterFunction = function(item:Object):Boolean

{ return Number(item) == numberToMatch; }

;
list2.refresh();

var list3:ListCollectionView = new ListCollectionView(list2);
list3.sort = new Sort();
list3.refresh();

trace(list1.length);
trace(list2.length);
trace(list3.length);

numberToMatch = 4;
list1.refresh();

trace(list1.length);
trace(list2.length);
trace(list3.length);

list1.source = list1.source;

trace(list1.length);
trace(list2.length);
trace(list3.length);
