Rerender not performed onselect
I have a tree which I want to use for navigation. Unfortunately the wanted page is not rendered when I select a node. The rendering is done when I expand/collapse a node. I modified the jboss-richfaces-3.0.1rc2-samples/tree-demo a little bit. I think that the timestamp should also be rerendered when a node is selected but it is only rerendered when I expand/collapse a node.
Thanks in advance.
