Error when running a JHeadstart generated two-level tree display

Question

Dear All,
I have a simple master detail VO/VO datamodel based on which I'd like to generate a two-level tree display. I've followed the JHeadstart dev guide meticulously.
When I run the page I get an error:
javax.faces.el.PropertyNotFoundException: Error getting property 'name' from bean of type oracle.jbo.uicli.binding.JUCtrlHierTypeBinding
It turns out that this generated code in a region file is the root cause:
<af:switcher facetName="#{node.hierType.name}">
<!-- DEBUG:BEGIN:TREE_NODE : default/misc/tree/treeNode.vm, nesting level: 2 -->
<f:facet name="MutatieSoortTypenNode">
<af:outputText value="#{node.Omschrijving}"/> </f:facet>
<!-- DEBUG:END:TREE_NODE : default/misc/tree/treeNode.vm, nesting level: 2-->
<!-- DEBUG:BEGIN:TREE_NODE : default/misc/tree/treeNode.vm, nesting level: 2 -->
<f:facet name="MutatieSoortenBijTypeNode">
<af:outputText value="#{node.Omschrijving}"/> </f:facet>
<!-- DEBUG:END:TREE_NODE : default/misc/tree/treeNode.vm, nesting level: 2-->
</af:switcher>
When I substituted the <af:switcher> .... </af:switcher> xml code by <af:outputText value="#{node.Omschrijving}"/>, the page displayed correctly.
Given the fact that the code is generated, there doesn't seem to be much that I can do about it.
We're using JDeveloper version 10.1.3.3.0 and JHeadstart version 10.1.3.2.41.
Any help or suggestion would be much appreciated.
Kind regards,
Ibrahim

Ibrahim,
I cannot reproduce this. You are using a non-production build. Can you upgrade to JHeadstart 10.1.3.2.52?
If the problem persists, you can work around it by creating a custom template for tree.vm which includes the af:switcher statement.
