I am adding to and removing from ArrayCollection - and when I do that, the Tree items refresh and are current. But when the items referenced by the ArrayCollection change, I am doing nothing.
Is there a way to "touch" the ArrayCollection so as to prompt Tree to reload (or reevaluate) its dataProvider and call labelFunction to generate updated rendering? Or is the preferred way to step walk through ArrayCollection and modify (in place) the changed objects?
