Assigning an array to a ListCollectionView

Question

I have a ListCollectionView that I want to add a listener to
so I can respond to changes, but the problem here is that I have to
assign an array to it. When I do this:
myListCollectionView = new ArrayCollection(myArray);
It removes all listeners. Is there any other way to force an
array into a ListCollectionView? When I do this:
myListCollectionView = myArray as ArrayCollection;
or
myListCollectionView = ArrayCollection(myArray);
I get an error.
Alternately, is there an event I can listen to on a TileList
that will let me know when the dataProvider has changed? I can't
seem to find anything that works.
P.S. Assigning a new ArrayCollection also seems to remove
ChangeWatchers as well.

Ok I ended up having to do this:
myListCollectionView.disableAutoUpdate();
myListCollectionView.removeAll();
for each (var thing:Thing in thingArray) {
myListCollectionView.addItem(thing);
myListCollectionView.enableAutoUpdate();
and then hooking into the onUpdateComplete event (fires after
the TileList redraws itself:
myTileList.addEventListener("onUpdateComplete",
myEventHandler);
