FindComponent in ExtendedDataTable

[phlebiac]

Hello folks,

I am currently trying to highlight all UIInput elements that have a validation issue during form processing.

I implemented a PhaseListener following this example : http://balusc.blogspot.com/2007/12/set-focus-in-jsf.html

My implementation:

{code}
public void beforePhase(PhaseEvent event) {
     FacesContext facesContext = event.getFacesContext();
     String focus = null; 
// Iterate over all client ID's with  messages.

     Iterator<String> clientIdsWithMessages =  facesContext.getClientIdsWithMessages();
     List<String> l = new ArrayList<String>();
          while (clientIdsWithMessages.hasNext()) {
               String clientIdWithMessages = clientIdsWithMessages.next();
               l.add(clientIdWithMessages);
               if (focus == null) {
                    focus = clientIdWithMessages;
               }

               if  (facesContext.getViewRoot().findComponent(clientIdWithMessages)  instanceof UIInput) {
                    UIInput input = (UIInput) facesContext.getViewRoot().findComponent(clientIdWithMessages);

                    input.getAttributes()
                         .put("styleClass", "highlight");
               }
          }
          facesContext.getExternalContext().getRequestMap().put("focus",  focus);
}
{code}

This works for nearly all my Input Elements but for those defined in Columns of rich:extendedDataTable:

{code:xml}
<rich:extendedDataTable
     value="#{controller.detailsDataModel}" var="item"
     width="100%" height="220px" enableContextMenu="false"
     sortMode="single" selectionMode="single"
     binding="#{controller.detailsDataTable}"
     id="tableTransportDetails"
     selection="#{controller.detailsSelection}"
     rows="5">
     <rich:column id="colTransportSelect" width="20%"
          label="#{msgs.labelTransportUnitCode_a}">
          <f:facet name="header">
               <h:outputText value="#{msgs.labelCode_a}" />
          </f:facet>
          <h:selectOneMenu style="width:100%;" 
               styleClass="inputRequired" 
               valueChangeListener="#{movementController.valueChangeResetStyleClassRequired}"
               id="transportUnitCodeSelect" 
               value="#{item.transportUnitCode}">
               <f:selectItems
                    value="#{codeListController.currentCodeListC0035}" />
                    <f:validator validatorId="codeListSelectionValidator" />
                    <a4j:support event="onchange" ajaxSingle="true"/>
          </h:selectOneMenu>
     </rich:column>
     <rich:column width="20%" id="colIdOfTransportUnits"
          label="#{msgs.labelIdentityOfTransportUnits_b}">
               <f:facet name="header">
                    <h:outputText value="#{msgs.labelIdentityOfTransportUnits_b}" />
               </f:facet>
               <h:inputText style="width:100%;"
                    styleClass="inputRequired"
                    valueChangeListener="#{movementController.valueChangeResetStyleClassRequired}"
                    id="identityOfTransportUnits"
                    value="#{item.identityOfTransportUnits}">
               <a4j:support event="onblur" ajaxSingle="true"/>
               </h:inputText>
     </rich:column>
{code}

What do I have to do, to access a single element inside an extendedDataTable row?

Any help is much appreciated.

I am using Richfaces 3.3.3 final
