My problem is the <f:param> is not known to _javascript_.
I need to read the node in _javascript_. Javscrit can read only the id that is available to the web page.
Any suggestions to creat this id in jsp, any pointers to such scripts?
Is there any other way to open the tree in a separate window, check a node and take the node id to the page that opened the tree window?
Please advise.
Thanks all.

You cannot use a valuebinding _expression_ for the id of a JSF
