ADF Tree Table Repeats Elements at All Levels in nodeStamp Facet

Question

Hi
I have an issue with ADF Tree Table (af:treeTable) whereby if I add a component to a group under the 'nodeStamp' facet it repeats for all levels in the tree even those outside the group.
Overview:
- 3-level master-detail structure created using ADF Business Components (3 view objects connected by 2 view links)
- ADF Tree Table based on master-detail
- Requirement to show 3 levels of data in the first column as a tree
- Tree table is rendering correctly showing values for 'node.FullName', 'node.DisplayValue' and 'node.HoursType' respectively in a 3 level tree.
- When another component is added to the top node in the tree ('node.FullName') for example some output text ('node.TimeBuildingBlockId'), it is displayed along side components 'node.DisplayValue' and 'node.HoursType' as well.
Code snippet:
      <af:treeTable value="#{bindings.PerPeopleFVO1.treeModel}" var="node"
                    selectionListener="#{bindings.PerPeopleFVO1.treeModel.makeCurrent}"
                    rowSelection="single" id="tt1" styleClass="AFStretchWidth"
                    horizontalGridVisible="true" verticalGridVisible="true"
                    disableColumnReordering="true" summary="Timecard Entry"
                    displayRow="selected" expandAllEnabled="false"
                    contentDelivery="immediate" autoHeightRows="24"
                    columnStretching="column:column1"
                    binding="#{pageFlowScope.TimecardMB.tree_binding}">
        <f:facet name="nodeStamp">
          <af:column id="c1" headerText="Partner Details" width="500">
            <af:group id="g4">
              <af:outputText value="#{node.FullName}" id="ot3"/>
              <af:outputText value="#{node.TimeBuildingBlockId}" id="ot1"/>
            </af:group>
            <af:outputText value="#{node.DisplayValue}" id="ot4"
                            inlineStyle="color:Green; font-weight:bolder;"/>
           <af:outputText value="#{node.HoursType}" id="ot5"/>
            <f:facet name="filter"/>
          </af:column>
        </f:facet>
        <f:facet name="pathStamp">
          <af:outputText value="#{node}" id="ot2"/>
        </f:facet>
   <af:column FROM HERE.........>
Any ideas greatly appreciated.

Hi,
Try using a switcher to distinguish all three levels of a tree. You can have three different facets, three different af:group 's.
When you add in one level, it will not repeat in the other level.
Please see the below snippet.
<af:tree value="#{bindings.RefBusinessUnitView1.treeModel}" var="node"
selectionListener="#{bindings.RefBusinessUnitView1.treeModel.makeCurrent}"
rowSelection="single" id="t1">
<f:facet name="nodeStamp">
<af:group id="g1">
<af:switcher id="s1"
facetName="#{node.hierTypeBinding.viewDefName}">
<f:facet name="model.RefBusinessUnitView">
<af:group id="g2">       
<af:outputText value="#{node.Code}" id="ot1"/>
</af:group>
</f:facet>
<f:facet name="model.RefProductFamilyView">
<af:group id="g3">
<af:outputText value="#{node.ProductFamilyName}" id="outputText1"/>
<af:outputText value="#{node.PName}" id="outputText2"/>
</af:group>
</f:facet>
</af:switcher>
</af:group>
</f:facet>
</af:tree>
