Hierarchical List View with Parent and detail as Table

Question

I have a requirement where in I need to show a list of items e.g Deparments and for each department I need to show the corresponding employees in a table
I used the listview component .I used the groupHeaderStamp containing a list item  to display the parent record and another liist item to display the child records. However , the child records are not getting displayed. If I comment the groupHeaderStamp, then the other records are getting displayed. Please help..
Basically , the below code from Using Tables, Trees, and Other Collection-Based Components - 11g Release 1 (11.1.1.7.0)  did not work . It showed up only the contents within the groupheader stamp I am using Jdeveloper 11.1.17.0
  <af:listView id="lv2" value="#{bindings.DepartmentsView1.treeModel}"
                       var="row"
                       selectionListener="#{bindings.DepartmentsView1.treeModel.makeCurrent}"
                       selection="single">
            <f:facet name="groupHeaderStamp">
              <af:listItem id="li3" >
                <af:outputText value="#{row.bindings.DepartmentName}" id="ot1"
                               inlineStyle="font-weight:bold;"/>
              </af:listItem>
            </f:facet>
            <af:listItem id="li2">
<af:outputText value="#{row.bindings.DeptNo}" id="ot10"
<af:outputText value="#{row.bindings.EmpName}" id="ot11"
</af:listItem>
</af:listView>
Please help.

Hi ..
Thanks for replying .
I created Dept , Emp and a view link. Instead of using the groupHeaderStamp facet  , I directly used the view link iterator within the a single listItem . The listItem shows the Dept attributes and the Emp view link iterator as a panelCollection. I was able to display the data as required . Now if I try to add an employee record to a table ,   I am getting the following error.
java.lang.ClassCastException: oracle.adfinternal.view.faces.model.binding.FacesCtrlHierNodeBinding cannot be cast to org.apache.myfaces.trinidad.model.CollectionModel .ue
This error appears during the following casting : CollectionModel cModel = (CollectionModel) table.getValue();
Could you please help.?
