Sean,
Thanks for the reply.
I removed the expand and collapse facets, I am now getting server-side tree
also.
But the problem is that server side tree is rendered in a non tiles page.
When I try to use it in a tiles page it is again giving the same error that
I had mentioned before.
Can you suggest what I should do.
Thanx and Regards
Rashmi

Please respond

Discussion"
Try removing the expand and collapse facets. Those are really only
meant for the client side version. Take a look at the server side
tree in the simple examples for an idea of how to set it up. You
should be able to modify the client-side trees in the examples using
the server-side examples as your guide.
HTH,
sean
