Hi
in my app i have a tree with contextMenu for each child.
If I try to add a node at runtime clicking on a button, and then rerender that tree, I've got an exception:

that is my code:

<a4j:outputPanel id="pnl_tree">
<rich:tree id="id_tree" reRender="pnl_container" nodeSelectListener="#{treeModelBean.processRichiesta}" switchType="client" ajaxSubmitSelection="true" >

 <rich:treeNodesAdaptor id="request" nodes="#{treeModelBean.requests}" var="req">
 <rich:treeNode iconLeaf="/resources/img/icons/16/Medical-invoice-information-16x16.png" icon="/resources/img/icons/16/health-care-shield-16x16.png" oncontextmenu="return false;" >
 <h:outputLabel value="Richiesta: #{req.id} - #{req.data}" />
 </rich:treeNode>

 <rich:treeNodesAdaptor id="impegn" var="imp" nodes="#{req.impegnList}">
 <rich:treeNode iconLeaf="/resources/img/icons/16/Medical-invoice-information-16x16.png" icon="/resources/img/icons/16/Medical-invoice-information-16x16.png" oncontextmenu="return false;">
 <h:outputLabel id="impm" value="Impegnativa: #{imp.id} - #{imp.descr}" />
 <rich:contextMenu event="oncontextmenu" attachTo="impm" >
 <rich:menuItem ajaxSingle="true" value="Aggiungi Esame" action="#{treeModelBean.addExam}" id="addEx">
 <a4j:actionparam value="{imp}" assignTo="#{treeModelBean.selectedImp}" />
 </rich:menuItem>
 <rich:menuItem ajaxSingle="true" value="Modifica Impegnativa" action="#{treeModelBean.editImp}" id="editImp">
 <a4j:actionparam value="{imp}" assignTo="#{treeModelBean.selectedImp}" />
 </rich:menuItem>
 <rich:menuItem ajaxSingle="true" value="Elimina Impegnativa" action="#{treeModelBean.delImp}" id="delImp">
 <a4j:actionparam value="{imp}" assignTo="#{treeModelBean.selectedImp}" />
 </rich:menuItem>
 </rich:contextMenu>
 </rich:treeNode>


 <rich:treeNodesAdaptor id="exam" var="ex" nodes="#{imp.examList}">
 <rich:treeNode iconLeaf="/resources/img/icons/16/blood-16x16.png" icon="/resources/img/icons/16/blood-16x16.png" oncontextmenu="return false;">

 <h:outputLabel id="exm" value="Esame: #{ex.id} - #{ex.cod}" />
 <rich:contextMenu event="oncontextmenu" attachTo="exm" >
 <rich:menuItem value="Modifica Esame" action="#{treeModelBean.editExam}" id="editEx">
 <a4j:actionparam value="{imp}" assignTo="#{treeModelBean.selectedImp}" />
 <a4j:actionparam value="{ex}" assignTo="#{treeModelBean.selectedExam}" />
 </rich:menuItem>
 <rich:menuItem value="Elimina Esame" action="#{treeModelBean.delExam}" id="delEx">
 <a4j:actionparam value="{imp}" assignTo="#{treeModelBean.selectedImp}" />
 <a4j:actionparam value="{ex}" assignTo="#{treeModelBean.selectedExam}" />
 </rich:menuItem>
 </rich:contextMenu>

 </rich:treeNode>

 </rich:treeNodesAdaptor>

 </rich:treeNodesAdaptor>

 </rich:treeNodesAdaptor>

 <a4j:support event="onselected" action="#{treeModelBean.doSomething}" reRender="pnl_req,pnl_ex,pnl_imp" />
</rich:tree>
</a4j:outputPanel>

<a4j:commandButton styleClass="bottone_lungo" oncomplete="Richfaces.showModalPanel('newRequestPanel');" action="#{treeModelBean.prepareNewRequest}" id="btnNewReq" value="Nuova Richiesta" reRender="pnl_tree" />

If I remove contextMenu the app add a node and show it correctly.

I'm using RF3.2.1 GA

Thanks to all
