    Problem with A4J re-render

      Hello...

      I am using ajax4jsf-1.1.0.jar with Sun's JSF RI 1.1. I am using a4j:commandLink to update my backing bean. Variables are getting updated in the backing bean, but my screen component is not getting updated or rerendered.

      The following is my code:

      <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
//ALL INCLUDE TAG LIBS
<f:loadBundle basename="resources.application" var="bundle"/>
<f:subview id="billsearch">
<html>
<body>
<script language="JavaScript" src="../scripts/lrrscript.js"></script>
<h:form id="billSearchForm" >
 <h:messages id="errorMess"/>
 <t:panelTabbedPane
 id="tabPanel" serverSideTabSwitch="false">

<%-- SIMPLE SEARCH TAB --%>
 <t:panelTab id="simpleSearch" label="Search" onkeypress="unsetFlag();" onclick="unsetFlag();">
 <h:inputHidden id="locationtype" value=""/>
 <%-- Some Content --%>


 </t:panelTab>

<%-- ADVANCE SEARCH TAB --%>
 <t:panelTab id="NewTabadvanceSearch" label="Advance Search">
 <t:panelTabbedPane
 id="subTabPanel" serverSideTabSwitch="false">

 <%-- HOME TAB --%>
 <t:panelTab id="subTabOne" label="#{bundle['lis.adv.search.tab.home']}">
 <h:panelGroup>
 <jsp:include page="AdvanceSearch/tabHome.jsp" />
 </h:panelGroup>
 </t:panelTab>

 <%-- DISPLAY SAVED CRITERIA TAB --%>
 <t:panelTab id="subTabEleven" label="Saved Search Criteria">
 <h:dataTable id="votetable" value="#{advanceSearchProcess.selectedCriteria}"
 var="searchResultsBean" binding="#{advanceSearchProcess.summarySearchUI}">
 <%-- nitrox:varType="beans.SearchResultsBean" --%>

 <h:column>
 <f:facet name="header">
 <h:outputText value="#{bundle.date}" style="width: 70px"/>
 </f:facet>

 <a4j:region id="stat2">
 <a4j:status for="stat2">
 <f:facet name="start">
 <h:graphicImage value="/images/ajax_process.gif" />
 </f:facet>
 <f:facet name="stop"/>
 </a4j:status>
 <a4j:commandLink reRender="votetable" styleClass="portletNav" actionListener="#{advanceSearchProcess.loadDetailVotes}" >
 <h:outputText value="#{searchResultsBean.detailsDisplayed ? '-' : '+'}" style="text-decoration: none"/>
 </a4j:commandLink>
 <h:outputText value="#{searchResultsBean.searchCriteriaId}"/>
 </a4j:region>
 </h:column>

 <h:column>
 <f:facet name="header">
 <h:outputText value="#{bundle.motion}"/>
 </f:facet>
 <h:panelGroup>
 <h:outputText value="#{searchResultsBean.userId}"/>
 </h:panelGroup>
 <h:panelGroup rendered="#{searchResultsBean.detailsDisplayed}">
 <h:outputText value="#{searchResultsBean.xmlSearchCriteria}"/>
 </h:panelGroup>
 </h:column>
 </h:dataTable>

 </t:panelTab>
 </t:panelTabbedPane>
 </t:panelTab>

 </t:panelTabbedPane>
</h:form>
</body>
</html>
</f:subview>


      The intention is that when I click on the link, the details displayed attribute will be set to true in my backing bean. So rerendering the screen would display my details.
      My Action Listener method is: 

      public void loadDetailVotes(ActionEvent e) {
 SearchResultsBean searchResultsBean = (SearchResultsBean) summarySearchUI.getRowData();

 if (searchResultsBean.isDetailsDisplayed()) {
 searchResultsBean.setDetailsDisplayed(false);
 } else {
 searchResultsBean.setDetailsDisplayed(true);
 }

 Utility.Log(Level.INFO, this, "EXIT loadDetailVotes");
 }


      The backing bean is getting updated as I could see that from my log:

      I am not really sure what might be the problem. I welcome and appreciate if someone can provide me with a hint on what might be the problem.

      Thanks.
