Af:tree with command link

Question

hi experts,
am using jdeveloper 11g version 11.1.1.5.0 - adfbc components - oracle db 10g.
am trying some examples regards,
af:tree with commandLink,
here what i did:
i achieved the af:tree with the help of some association between two tables and then i exposed in ui,
you can see in this pics1 :
http://www.4shared.com/photo/kGE2M1yl/pics1.html
and then af:tree output can also seen in pics2:
http://www.4shared.com/photo/GQTB9icb/pic2.html
this is the code for af:tree
<af:tree value="#{bindings.ApplBusFunSuiteView1.treeModel}"
                     var="node"
                     selectionListener="#{bindings.ApplBusFunSuiteView1.treeModel.makeCurrent}"
                     rowSelection="single" binding="#{backing_untitled1.t1}"
                     id="t1">
              <f:facet name="nodeStamp">
                 <af:outputText value="#{node}"
                                 binding="#{backing_untitled1.ot1}" id="ot1"/>
              </f:facet>
            </af:tree>ok thing which i did all are ok.
but my need is :
you may see in pics2.
http://www.4shared.com/photo/GQTB9icb/pic2.html
i make red mark on the on a child.
here am going to explain my need
in the picture you can see CRM as parent
MKG as first child
MKG3200 as last child.
command link should be appeared.
when i click that it will navigate to the corresponding page.
for eg: if i click MKG3200 navigate to the MKG3200 page.
how can i do this.? i need some guidance.
sorry for my poor english.

}i get my output. what i need.
you must check whether am going correct?
please suggest me.
sorry : pulling this thread to up.
