    Shivaji Byrapaneni Newbie

      Hi There,

      I had my jsp included with rich:listShuttle when i tried to do any action after the listShuttle had been populated im getting thsi error

      Component nominationSystemHome:listShuttle has invalid value expression com.vo.ApproveVO@fea10aee"

      im using ths in my jsp
      <rich:listShuttle sourceValue="#{approveCoursesBean.nominatedList}"
       targetValue="#{approveCoursesBean.approvedList}" var="items"
       sourceCaptionLabel="Nominated people"
       targetCaptionLabel="People to approve" id="listShuttle"
       <rich:column width="18">
       <h:graphicImage value="#{items.iconURI}" width="25px" height="25px"></h:graphicImage>
       <h:outputText value="#{items.label}"></h:outputText>

      and my mbean had this

      private ArrayList<ApproveVO> approvedList = new ArrayList<ApproveVO>();
       private ArrayList<ApproveVO> nominatedList = new ArrayList<ApproveVO>();

      with setters and getters

      and my VO is this

      package com.vo;
      import java.io.Serializable;
      public class ApproveVO implements Serializable {
       private String iconURI;
       private String label;
       public ApproveVO(String iconURI, String label) {
       this.iconURI = iconURI;
       this.label = label;
       public String getIconURI() {
       return iconURI;
       public void setIconURI(String iconURI) {
       this.iconURI = iconURI;
       public String getLabel() {
       return label;
       public void setLabel(String label) {
       this.label = label;
       public boolean equals(Object obj) {
       if (this == obj)
       return true;
       if ((obj == null) || (obj.getClass() != this.getClass()))
       return false;
       ApproveVO approveVO = (ApproveVO) obj;
       if (approveVO.iconURI.equals(this.iconURI)
       && approveVO.label.equals(this.label))
       return true;
       return false;
       public int hashCode() {
       int hash = 7;
       hash = 31 * hash;
       hash = 31 * hash + (null == this.label ? 0 : this.label.hashCode());
       return hash;
