    Trouble in rerender multiple components on value change

      Hi Team

      I am having trouble in rerendering multiple components on change of value of radio button. My code is

      JSP Code:---

      <h:selectOneRadio value="#{siteRequirementBean.whetherWantToAddFloorSelected}" id="selectOneRadioId" >
      <f:selectItems value="#{siteRequirementBean.whetherWantToAddFloorValues}" />
      <a4j:support event="onclick" actionListener="#{siteRequirementBean.displayFloor}" ajaxSingle="true" reRender="dataTableFloorId,PanelGroupUserGroupAssocId" />
      </h:selectOneRadio>

      Relavant backing bean method:--
      ActionListener in BackingBean, ?Backing Bean is in session Scope ?

      public void displayFloor (ActionEvent event)
      {
      if (whetherWantToAddFloorSelected == null)
      {
      whetherWantToAddFloorSelected = new Integer(0);
      displayUserGroupAssoc = false;
      }
      else if (whetherWantToAddFloorSelected == 1)
      {
      createFloor ();
      displayUserGroupAssoc = true;
      }
      else if (whetherWantToAddFloorSelected == 0)
      {
      floorRequirementSetMetaDataList.clear ();
      displayUserGroupAssoc = false;
      }
      }

      JSP Code of components which are required to be rerendered:---

      <h:dataTable id="dataTableFloorId" value="#{siteRequirementBean.myFloorList}" var="var1">

      <%-- Code for DataTable goes here--%>

      </h:dataTable>


      <h:panelGroup id="PanelGroupUserGroupAssocId" rendered=? displayUserGroupAssoc?>
      <h:outputText value="Select Profile" />
      <h:graphicImage url="../../images/spacer.gif" width="15" height="5" />
      <h:selectOneMenu value="#{siteRequirementBean.selectedUserProfile}" id="selectOneMenuId222">
      <f:selectItems value="#{siteRequirementBean.userProfileValues}" />
      <a4j:support event="onchange" actionListener="#{siteRequirementBean.loadProfiles}" ajaxSingle="true" reRender="dataTableUserProfileId" />
      </h:selectOneMenu>

      </h:panelGroup>




      On change of value of radio button, the displayFloor method in the backing bean gets called, it create the content for the ?dataTableFloorId? & sets the rendering property [displayUserGroupAssoc] for panelGroup to true. The datatable comes fine with the data, but the panelGroup is not getting displayed. In debug mode I confirmed that value of the property displayUserGroupAssoc is set as true when user changes the value of radio button?..
      Please let me have your valuable input ??

      Thanks & Regards.
