      Hi There,

      I had a sitaution in which when i select a value form the combo box a action listener in my backing bean need to be triggered. For that i had this code in my JSP

      <!doctype html public "-//w3c//dtd html 4.0 transitional//en">
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<!-- RichFaces tag library declaration -->
<%@ taglib uri="http://richfaces.org/a4j" prefix="a4j"%>
<%@ taglib uri="http://richfaces.org/rich" prefix="rich"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<f:subview id="ApproverView">
<h:panelGrid columns="2">
 <h:outputText value="Course Name to approve : " />
 <rich:comboBox value="#{approveCoursesBean.courseName}"
 directInputSuggestions="true" defaultLabel="Enter Course Name">
 <a4j:support event="onSelect" rendered="approveLS"
 actionListener="#{approveCoursesBean.populateNominationListBasedOnCourseSelected}" />
 <f:selectItems value="#{nominationSessionBean.courseNames}" />
 </rich:comboBox></h:panelGrid>
<rich:spacer height="20" />

<rich:listShuttle sourceValue="#{approveCoursesBean.approvedList}"
 targetValue="#{approveCoursesBean.nominatedList}" var="people"
 sourceCaptionLabel="Nominated people"
 targetCaptionLabel="Approved people" id="approveLS"
 converter="approveCoursesConverter">
 <rich:column width="18">
 <h:graphicImage value="#{people.iconURI}" width="30px" height="30px" />
 </rich:column>
 <rich:column>
 <h:outputText value="#{people.userId}" />
 </rich:column>
 <rich:column>
 <h:outputText value="#{people.userName}" />
 </rich:column>
 <!--<a4j:support event="onlistchanged" reRender="toolBar" />
 <a4j:support event="onorderchanged" reRender="toolBar" />
-->
</rich:listShuttle>
</f:subview>


      and the above page will be included into below page as shown 

      <!doctype html public "-//w3c//dtd html 4.0 transitional//en">

      in my backing bean i had teh associated action listener like this 

      package com.managedbeans;

import java.util.ArrayList;

import javax.faces.event.ActionEvent;
import javax.faces.model.SelectItem;

import com.entities.CourseDetailsEO;
import com.logger.NominationLogger;
import com.vo.ApproveVO;

public class ApproveCoursesBean extends NominationBaseBean {
 private final String className = this.getClass().toString();
 private String courseName ;
 private ArrayList<ApproveVO> nominatedList = new ArrayList<ApproveVO>();
 private ArrayList<ApproveVO> approvedList = new ArrayList<ApproveVO>();

 public ArrayList<ApproveVO> getNominatedList() {
 return nominatedList;
 }

 public void setNominatedList(ArrayList<ApproveVO> nominatedList) {
 this.nominatedList = nominatedList;
 }


 public String getCourseName() {
 return courseName;
 }

 public void setCourseName(String courseName) {
 this.courseName = courseName;
 }

 public ArrayList<ApproveVO> getApprovedList() {
 return approvedList;
 }

 public void setApprovedList(ArrayList<ApproveVO> approvedList) {
 this.approvedList = approvedList;
 }


 public String populateCourseListToApprove() {
 final String methodName = "populateCourseListToApprove";
 NominationLogger.logMethodEntry(className, methodName);
 ArrayList<CourseDetailsEO> courseList = getNominationSessionBean().getCoursesList();
 getNominationSessionBean().setCourseNames(new SelectItem[courseList.size()]);
 CourseDetailsEO courseDetailsEO = null ;
 for(int a = 0; a < courseList.size() ; a++){
 courseDetailsEO = courseList.get(a);
 getNominationSessionBean().getCourseNames()[a] = new SelectItem(courseDetailsEO.getCourseName());
 }
 NominationLogger.logMethodExit(className, methodName);
 return null;
 }

 public String populateNominationListBasedOnCourseSelected(ActionEvent event) {
 final String methodName = "populateNominationListBasedOnCourseSelected";
 NominationLogger.logMethodEntry(className, methodName);
 NominationLogger.info(this.courseName);
 NominationLogger.logMethodExit(className, methodName);
 return null;
 }
 }




      i cant see the a4j:support getting triggered. i even tried the valuechangelistener option of rich:combobox and that even didnt help.

      please correct me.
      many thanks in advance.
