Hello,
I am also working on the same senario,but i not able to reconstruct the tree
with the child nodes given a parent node on click of a particular node.I
have overriden the onNodeClickedEvent() of the AbstractTree but the tree in
the webpage does',t show the child nodes on refresh.
Plz Help .
Thanks and Regards.
