retrieve super-parent in rich:tree node

[mcremolini]

Hi all,

how can I retrieve the parent of a node in a tree?
In particular I would like to know the parent at any level navigation tree.

For example:

in the following tree...

A__
     | __x
         | __Y
             | __Z

if I position it over Z  node, I would like to retrieve the reference to A.
This is needed to dynamically change a context menu based on the super-parent of a node.

Thanks for your help.

Hi Matteo,

rich:tree can be used in several different ways. Can you please post page code to see which one you are using?

Hi,

i use the   tag

<rich:recursiveTreeNodesAdaptor>

<rich:tree id="mittDestTree" style="width:300px" switchType="ajax"
                        ajaxSubmitSelection="true" ajaxSingle="false"
                        iconLeaf="/images/users_grp.gif" icon="/images/users_grp.gif"
                        iconCollapsed="/images/tree/collapsed.gif"
                        iconExpanded="/images/tree/expanded.gif"               
                        reRender="treePanel" status="ajaxStatus" >

                        <rich:recursiveTreeNodesAdaptor
                            roots="#{mittDestViewBean.sourceRoots}" var="currItem"
                            nodes="#{currItem.nodes}" > 
                            <rich:treeNode id="nodo">
                                <h:outputText value="tipo:#{currItem.mittDest.tipo_nodo} unita:#{currItem.mittDest.id_unita} #{currItem.miDest.descr_unita} #{curtItem.mittDest.regAssoc}"/>

                            </rich:treeNode>
