Adf treeTable issue

Question

HI again!
I 'm a bit confused about using an adf treeTable component (adf faces 11g).
I've created a down-hierarchy tree with root nodes and child nodes. Now i need to bind an action listener to child nodes only. So i've defined the nodeStamp facet's component as a commandLink and assigned the appropriate action listener to it.
The problem is that it fires now when i click a root node link as well as when i click a child node link. Is there any solution for this?
It would be great at all if it were possible to define the root node component to be something like output text (not command component) and the child component to be a command link.
Thanks in Advance. Alex.

You can use a switcher component inside the tree to display different things based on the tree node type #{node.hierType.structureDefName}.
              <af:tree value="#{bindings.LocationsView1.treeModel}" var="node"
                       selectionListener="#{bindings.LocationsView1.treeModel.makeCurrent}"
                       rowSelection="single" id="t1"
                       binding="#{backing_index.tree}">
                <f:facet name="nodeStamp">
                  <af:group id="g1">
                    <af:switcher id="s1" defaultFacet="drag"
                                 facetName="#{backing_index.allowDrag}">
                      <f:facet name="drag">
                        <af:panelGroupLayout id="pgl2">
                          <af:outputText value="#{backing_index.allowDrag}" id="ot3"/>
                          <af:outputText value="#{node}" id="ot1">
                            <af:attributeDragSource attribute="value"/>
                          </af:outputText>
                        </af:panelGroupLayout>
                      </f:facet>
                      <f:facet name="nodrag">
                        <af:group id="g2">
                          <af:outputText value="#{backing_index.allowDrag}#{node.selectedRow}" id="ot4"/>
                          <af:outputText value="#{node}" id="ot2"/>
                        </af:group>
                      </f:facet>
                    </af:switcher>
                  </af:group>
                </f:facet>
              </af:tree>
