Matthew, The Tree component doesn't suck that bad, try a different title. I'll answer your question though, openItems uses references(unique id's), it's not majik man. You have to understand instance references, then you can say the Tree doesn't suck, I just didn't understand it.
This is the key, right here; _openItems[itemToUID(item)] = item; What this means is, if you do not supply the items with the same instance(unique), this property will never work. Sounds like you need to do a little leg work and save the state of your tree before you set the dataProvider, then create a new openItems Array with the current instances that ARE IN the tree. What kind of objects are held in your dataProvider? ... Object, or a custom model class?
