ADF : TreeTable: Read selected Node from ADF TreeTable.

TreeTable: Read selected Node from ADF TreeTable.


I have 2 level of tree structure as shown below
   ObjectMainVO
        |_ ObjectFakeVO
                

My requirement is :
  User can select any row from the above heirarchy
  In my bean class i have to find, what VO user has selected and do some operation.

###################In JSPX page ################################################
1. remove ..makeCurrent from treeTable and call TreeSelectionListner (since we are executing makeCurrent from bean class)
---------------------------------------------------------------------------------
<af:treeTable value="#{bindings.ObjectMain2.treeModel}" var="node"
                      selectionListener="#{backingBeanScope.backing_ObjectMain_ObjectFake_MapView.TreeSelectionListener}"
                      rowSelection="single"
                      binding="#{backingBeanScope.backing_ObjectMain_ObjectFake_MapView.tt1}"
                      id="tt1">
          <f:facet name="nodeStamp">
            <af:column id="c1">
              <af:outputText value="#{node}" id="ot2"/>
            </af:column>
          </f:facet>
          <f:facet name="pathStamp">
            <af:group binding="#{backingBeanScope.backing_ObjectMain_ObjectFake_MapView.g1}"
                      id="g1">
              <af:outputText value="#{node}"
                             binding="#{backingBeanScope.backing_ObjectMain_ObjectFake_MapView.ot1}"
                             id="ot1"/>
            </af:group>
          </f:facet>
        </af:treeTable>

##############################In Bean Class ##################################
1. Execute the makeCurrent for parentVO manually
2. get the selected key (make sure that parent and child VO has unique key)
3. Check selected node is what type of VO in if else condition
