That'd work... but I'd be more inclined to save off a copy of my initial
data when I stick it in the ArrayCollection, then on submit walk the two
collections seeing what changed. But, that's really just my preference.

What u can do is to addEventListener for the
[mx.events.CollectionEvent.COLLECTION_CHANGE] event type.
When u get a call back u can check the [kind] and [location] property
of CollectionEvent to determine whether the collection has been
modified in any way. The [kind] constant that you're looking for is
[mx.events.CollectionEventKind.UPDATE].
This way you don't have to iterate your array collection. The draw
back is u have to store what has been modified even if the user
doesn't click submit.
