tree2 node expanded problem

I have a tree2 ‘Root’ node containing items which the User can select

If the User selects an item they can then hit a ‘Remove’ button

The screen gets refreshed and the item is gone

This operates correctly until the last item gets ‘Removed’ – when I get an error

Servlet.service() for servlet jsp threw exception java.lang.IllegalStateException:

Encountered a node [0] + with an illogical state. Node is expanded but it is also considered a leaf

(a leaf cannot be considered expanded.

In my ‘Remove’ code I have

List l = tree.getChildren();

if(l.size() == 0){

tree.setLeaf(true);

}

But this does NOT then seem to propagate out to the GUI rendered component

I would have expected the Expanded state of a node to be false if the node has ZERO children

Is this a bug, or is there something I’ve missed

Thanks
