The meaning of tree.updateTree(target) is to refresh changed parts of
the tree during ajax request (assuming the model fired proper
listeners).
The problem with DnD tree is that it's more complicated than just
reordering DOM entries and then notifying the server. Anyway, if you
want to make sure that the whole tree is redrawn call invalidateAll on
it before sending to ajaxrequesttarget.
