Treeview : Client side expand node

[ROS]

Hi,

My treeview is on a HTML page implemented using Javascript and *.HTC file.

I am trying to expand a node in JavaScript using...

<CODE>

TreeNode.setAttribute("EXPANDED", true);

<CODE>

But I get an error "'event' is null or not an object" error ...I get this
error only on nodes i have added programatically added and not nodes which
are added using XML initially. This is a load-on-demand tree so the root
level is loaded using XML but the remainder nodes are loaded in the onexpand
event programatically.

Any help will ge highly appricited....
