Ok all your help is welcome, and don't worry, reassign them to you if you think to work on
them, I'm not jealous :-) .

> I have a TreeView with a TreeViewSelectionListener, but the listener doesn't get invoked
when a item is removed from the tree.
> I do : tree.getTreeData().remove( tree.getSelectedNode());
> tree is refreshed : the removed node is no longer shown, no node is selected but the
listener is not invoked. 
> Looked at the code :
> in TreeView#itemsRemoved(), clearAndDecrementPaths() is invoked and returns 0. But Listeners
are only invoked when > 0 is returned. 
> see attached example comparing a TreeView to a ListView
