problems with node deletion after richfaces 4 migration

[mythilisanthanam]

Migrating my project from richfaces  3 to 4.  i have a delete functionality of the  child node from parent. i have to  access the  parent id fro m child so that it can be passed to bean for framing delete queriy.

But the var attribute of treemodeldaptor does not give details of parent from child. pls help.. had tried below workaround from another place....but  failed...

rich:tree ... var="node"> <!-- Add a 'var' attribute -->
   <rich:treeModelAdapter>
   <c:set var="vm_host" value="#{node}"/>
   <rich:treeNode .../>
   <rich:treeModelAdapter>
   <c:set var="vm_guest" value="#{node}"/>
   <rich:treeNode .../>
   </rich:treeModelAdapter>
   </rich:treeModelAdapter>
</rich:tree>

on trying to access vm_host from my second adapter, it is overwritten with value of vm_guest only

I don't think I understand, the tree simply displays your data, if you need to make changes in the data model that's up to you to implement it.

Let me articulate it differently.. I am trying to display tree. similar to ex above:

Vm-hosts and the vm -guests under the hosts. consider scenario, where the user wants to remove a guest from host.. I have to pass  both the host id and guest id to bean to frame the delete query. now, to set a background, the whole pbm surfaces out  in richfaces 4 because of the removal of "var" variable at the  level of each "treemodeladaptor".

Please suggest  if you have a workaround to access the host and guest id at a time from client. I don't want to restructure the bean object  and rewrite considering the time given for migration..

Why not just get the guest id (which I assume works ok) and then find its parent in the bean?
