Multiselected-Tree: Define some unselectable nodes

Hi,

I am newbie in vaadin.
I programed the small Tree (as MultiSelectMode.SIMPLE) and I want to define some nodes as
unselectable
nodes.
Is this possible? Have you a hint for me?

I used ‘tree.setNullSelectionItemId(XXX)’ but tree dosn’t support this. I received:
java.lang.UnsupportedOperationException

I need somthing like ‘setSelectable(boolean selectable)’ not only for hole tree, but also for nodes too.

Thanks from Frankfurt/Germany

Hi,

I searched via google, but find nothing for my case in Vaadin.
Is there a way to catch the select-Listener?

But, it seems not to work (2 and 3 years old hints).
