Yes, please, that title is a bit offensive.
If your data was xml, and you had unique id's on the leaf noded, this would be pretty easy. Just maintain a list of visible (ancestor chain is open) leaf node ids. To restore the tree, loop over that list, using e4x to find the node, then use parent() in a loop to climb back up the tree, opening nodes as you go, until you reach an open node or the root. If that won't work for you then you might have to store a set of delimited paths, then to restore the tree, parse the paths to navigate to and open each node.

I need help :) 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?

The tree will have two branches. each branch will have several children. Basically a list of files. So the user will upload a new file by clicking an browsing for a new file. I then as AMFPHP to give the list of files again and update the ArrayCollection with new data. Before I ask for the new ArrayCollection of data I store the try components open items like this tempOpenItems = mytree.openItems; after the new data is set I then would like to say mytree.openItems = tempOpenItems; this does not work. Has anyone figured out how to add new data to the Tree dataProvider and maintain the Trees view state of open Items? thanks, matthew -- Teoti Graphix, LLC http://www.teotigraphix.com <http://www.teotigraphix.com> Teoti Graphix Blog http://www.blog.teotigraphix.com <http://www.blog.teotigraphix.com> You can find more by solving the problem then by 'asking the question'.
