Hello,
I have a page that contains a rich:tabPanel. This tabpanel contains 2 pages.

<rich:tabPanel id="pagetabpane" switchType="client">
<rich:tab id="page1tab" label="#{msg.pageLabel} 1">
...
</rich:tab>
<rich:tab id="tabpage2" label="#{msg.pageLabel} 2">
...
</rich:tab>
</rich:tabPanel>

The second page contains a rich:dataTable.

<rich:dataTable border="1" width="100%"
 id="nozzletable32" value="#{processBowlModuleService.nozzles}" var="nozzle"
 onRowMouseOver="onOverTable(this);"
 onRowMouseOut="onOutTable(this);"
 onRowClick="onClickTable(this);checkAjaxFire('#{nozzle.name}');" rowClasses="tableRowClass">

 <h:column>
 <f:facet name="header">
 <h:outputText id="text4050" value="#{msg.nameLabel}"/>
 </f:facet>
 <h:outputText id="text20472" value="#{nozzle.name}"/>
 </h:column>
 <h:column>
 <f:facet name="header">
 <h:outputText id="text0293838" value="#{msg.statusLabel}"/>
 </f:facet>
 <h:outputText id="text4054" value="#{nozzle.status}"/>
 </h:column>
 <h:column>
 <f:facet name="header">
 <h:outputText id="text2349292" value="#{msg.flussmesserLabel}"/>
 </f:facet>
 <h:outputText id="text4055" value="#{nozzle.durchfluss}"/>
 </h:column>
 </rich:dataTable>

The problem is that everytime the dataTable gets reRendered, I get an "duplicated component ID" - Exception (from the dataTable; the id's from the columns get duplicated (???)).
When I change the switch type of the rich:tabPanel to ajax, I even can't open the page containing the dataTable (Duplicated Component Id).
When the switch-type is set to client, the datatable gets rendered once, but on every reRender I get the Exception.
Any suggestions?
