As a last resort, you can re-assign the dataProvider. That should definitely cause the tree to refresh. In 1.5, we could do myTree.dataProvider = myTree.dataProvider;

Subject: Re: [flexcoders] Re: F2b3: e4x XML object as Tree dataprovider, how to refresh tree display?
Actually, let me clarify that a bit. I can't get the Tree to show new nodes added to the root node. If I add nodes to child nodes, they show up when calling invalidateList(). The root node is the problem. I did a trace of the Tree's dataprovider after adding to the root node and the new children are in the XML. Must be a problem with the Tree's refresh logic.

I've noticed one other problem: If a Tree's showRoot property is set to false, not even calling invalidateList() will refresh the display. In fact, I can't find any way to get the Tree to refresh in such a case. Any ideas?

Post beta3, changes to XML will automatically get updated in the Tree
control. And you won't be required to go through XMLListCollection
but you can simply make changes to the XML model itself, e.g. delete,
+, appendChild, etc.
You're seeing a bug in the b3 Tree where the collection events aren't
being handled properly.
