How to access data values from root to child node (whole selected path) of rich:tree

[vjavadev]

hello,

I am working with richfaces 4.2.1 final.

I am using rich:tree with nested <rich:treeModelAdaptor>. As, var attribute is common for all nested levels, Can you please suggest me how to access the corresponding parent node value when a child node got selected. I need to retrieve the all node objects of the selected path from root to the selected child.

My code is pasted below. Please suggest me.

<rich:tree binding="#{aa.tree}" id="searchTree1" var="node" toggleType="client"

                                                    selectionType="ajax" selectionChangeListener="#{aa.onSelection}">

                                                    <rich:treeModelAdaptor   nodes="#{adverseEvent.productList}"

                                                         leaf="false" >

                                                        <rich:treeNode id="#{aa.counter()}"  binding="#{aa.node}" expanded="#{true}">

#{node.name}

                                             </rich:treeNode>

                                                        <rich:treeModelAdaptor nodes="#{node.productExposureList}"

                                                            leaf="false">

                                                            <rich:treeNode expanded="#{true}">

                                   #{node.name} 

                                   <a4j:commandButton id="add" value="edit"  action="#{aa.methoda(node1)}" />

                                          </rich:treeNode>

                                                            <rich:treeModelAdaptor

                                                                nodes="#{node.productExposureDoseList}" leaf="false">

                                                                <rich:treeNode  value="#{aa.dose1}" expanded="#{true}">

                  #{node.name}   hh    #{node1.name}                       <a4j:commandButton id="add" value="edit"  action="#{aa.methoda(node1.name)}" />

                                </rich:treeNode>

                                                                <rich:treeModelAdaptor

                                                                    nodes="#{node.intervalDetailsList}" leaf="true">

                                                                    <rich:treeNode  value="#{aa.interval1}" expanded="#{true}">

intervallllllllllll     #{node.intervalUnits}

</rich:treeNode>

                                                                </rich:treeModelAdaptor>

                                                            </rich:treeModelAdaptor>

                                                        </rich:treeModelAdaptor>

                                                    </rich:treeModelAdaptor>

                                                </rich:tree>

any workarounds here to access the "var" of the parent node from child? I want id of parent to be accessed from child. how can node deletion from parent be done without access to the parent id? Am I missing something?
