You would use the dataDescriptor to getChildren() and walk those children collections as well.

Thanks Alex Maybe I'm misunderstanding. I would not how to get to the top level objects, but what about the sub-level objects? Say I dont know how many levels the collection is nested? Let's say this is my function: private function expandTree(event:CollectionEvent):void { if(event.kind == CollectionEventKind.REFRESH) { var parentItems:XMLList = sessionsByDateTree.dataProvider.children(); doExpand(parentItems); function doExpand(items:XMLList):void { var len:int = items.length(); // loop through collection backwards for (var i:int = len-1; i >= 0; i--) { var childList:XMLList = items[i].children(); //sessionsByDateTree.expandChildrenOf(*what object am i passing in?*, true); //if this node has children, let's recurse! if (childList.length() > 0) { doExpand(childList); } } } } as you can see, my recursor is completely ignorant of what level it is currently in. Will I need to track that?
