Subject Re: Monitor collection change
Date Wed, 29 Apr 2015 18:39:22 GMT
Probably easier to do addEventListener(CollectionEvent.COLLECTION_CHANGE).

That will pick up changes to the collection, but not to properties in
object in the collection.  To do that, you will need to listen to each
object in the collection.
