    reRender in a4j:commandLink is not working

      Need some help.
      I have JSF codes as the followings:
      It will call backing bean Dashboard2Bean publish function to update publish status in database then re-fetch data then rerender the same table cell to refresh publish status.
      I verified that backing bean Dashboard2Bean publish is working.
      I specify the reRender attribute as dashboard_cell_45768_35 if the id of containing table cell is dashboard_cell_45768_35 in a4j:commandLink. Also I set limitToList="true" ajaxSingle="true". I inspect it under Firebug. Everything looks O.K. However, reRender is not working.

      <t:dataList id="subProfileList" var="profileAssoc" value="#{product.dashboardProfileAssocs}" rowIndexVar="currentRow">
       <td id="dashboard_cell_<h:outputText value="#{product.id}" />_<h:outputText value="#{profileAssoc.profile.id}" />" >
       <t:outputText rendered="#{profileAssoc.displayStatus == 'Pending'}">
       <img src="/panda/images/dashboard/icon_status_mini_pending.png" alt="Pending" />
       <a4j:commandLink reRender="dashboard_cell_#{product.id}_#{profileAssoc.profile.id}" action="#{Dashboard2Bean.publish}" limitToList="true" ajaxSingle="true" value="publish">
       <img src="/panda/images/dashboard/icon_menu_publish.png"
       <f:param name="publishProductId" value="#{product.id}"/>
       <f:param name="publishProfileId" value="#{profileAssoc.profile.id}"/>
       </a4j:commandLink>
       </t:outputText>
       <t:outputText rendered="#{profileAssoc.displayStatus == 'Published'}">
       <img src="/panda/images/dashboard/icon_status_mini_published.png" alt="Published" />
       </t:outputText>
       <t:outputText rendered="#{profileAssoc.displayStatus == 'Expired'}">
       <img src="/panda/images/dashboard/icon_status_mini_expired.png" alt="Expired" />
       </t:outputText>
       </td>
      </t:dataList>

          This will work only using a4j data iteration components. tomahawk UIData just not provides any mechanisms to update them partially.

          • 2. Re: reRender in a4j:commandLink is not working, resolved, bu

            I get partial render work beautifully by replacing <t:dataList> in both outer loop and inner loop with <rich:dataList> and also add ajaxKeys in both <rich:dataList>.

            However, I get into new bug after I switch to <rich:dataList> . Dashboard view render well when I display the first time. When I switch date and re-fetch data and display the second time, I got
            java.lang.IllegalStateException: duplicate Id for a component dashboardForm:productList:subProfileList:j_id61
            org.ajax4jsf.application.AjaxStateManager$TreeStrutureNode.apply(AjaxStateManager.java:418)

            org.ajax4jsf.application.ViewHandlerWrapper.renderView(ViewHandlerWrapper.java:108)

            I specify add whenever I can. I still got the same error. What should I do ?

              seems you using session scoped binding. It will not works fine in JSF in general.

              • 4. Re: reRender in a4j:commandLink is not working

                Yes. You are absolutely right. I took out the binding and replace ithem with passing parameters this morning. It's working now.
                Thanks.
