Hi,
could you explain HOW you delete the nodes? Do you click on a node,
represented by a commandLink or do you use checkboxes..or..
I had a similar problem changing the treeModel of tree (not tree2).
I implemented my own sorting for a treeTable using t:tree. After
a click on a commandLink which triggers the sorting the renderer rendered
the old treeModel, not the updated one.
The solution was to use the action attribute of the commandLink in
combination with the page navigation.
Regards,
Christian
