> TreeState.expandNode(UITree, TreeRowKey) is apparently supposed to expand the node at the specified key, going recursively up along its parents and opening those as well. However, there is an if-statement which skips this logic for leaf nodes (for no apparent reason since the traversal is going up not down). I would expect this expansion to also work for leaf nodes.
> Offending code snippet:
> if (!tree.isLeaf()) {
> 	TreeRowKey key = rowKey;
> 	
> 	while (key != null && key.depth() != 0) {
> 		addQueuedState(key, NodeState.EXPANDED);
> 		key = (TreeRowKey) tree.getParentRowKey(key);
> 	};
> 	
> }
> Ugly workaround exists: add a dummy child to a leaf node, expand, and then remove the dummy child.
