rich:listShuttle-Property not found on type java.lang.String

[khaled_288]

I'm useing <rich:listShuttle> tag and i pass to it 2 lists : ArrayList
the lists are displayed correctly but when the select items and submit the form, the below exception is raised.

Service (value object):

public class Service implements Serializable
// 3 properties + getters + setters

GetPackage (backing bean)

public class GetPackageInfo extends SuperBean {
 private ServicePackage pack = new ServicePackage();
 private List<Service> services;
 private List<Service> selectedList = new ArrayList<Service>();
 private List<Service> availableList = new ArrayList<Service>();

 private boolean saved = false;

 public GetPackageInfo() throws Exception{
 super();
 initOptions();
 }

 public String update(){
 // update package info
 }

 private void initOptions(){
 // lookup the lists
 }

}

JSP

<rich:listShuttle orderControlsVisible="false" var="service" fastOrderControlsVisible="false" sourceValue="#{getPackageInfo.availableList}" targetValue="#{getPackageInfo.selectedList}">

<h:column>
<h:outputText value="#{service.englishName}" />
</h:column>
</rich:listShuttle>

Exception (raised only on submit)

FIXED

by following steps:

1- adding a converter

import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;

import com.elm.carportal.beans.Service;
import com.elm.carportal.web.util.WebConstants;
import com.elm.carportal.web.util.WebUtil;

public class ServiceConverter implements javax.faces.convert.Converter{

 public Object getAsObject(FacesContext context, UIComponent component,
 String value) {

 int index = value.indexOf(':');
 Service service = new Service();
 service.setId(Integer.valueOf(value.substring(0, index)));
 service.setEnglishName(value.substring(index + 1));

 return service;
 }

 public String getAsString(FacesContext context, UIComponent component,
 Object value) {
// get object as string
 }

}

2- register the converter in faces-config.xml:

<converter>
 <converter-id>serviceConverter</converter-id>
 <converter-class>com.elm.carportal.web.converters.ServiceConverter</converter-class>
 </converter>

3- add the converter attribute to

<rich:listShuttle orderControlsVisible="false" var="service" fastOrderControlsVisible="false" sourceValue="#{getPackageInfo.availableList}" targetValue="#{getPackageInfo.selectedList}" converter="serviceConverter">

<h:column>
<h:outputText value="#{service.englishName}" />
</h:column>
</rich:listShuttle>

4- finally in Service override the value object equals() method:

public boolean equals(Object obj) {
 if (this == obj){
 return true;
 }
 if (obj == null){
 return false;
 }
 if (getClass() != obj.getClass()){
 return false;
 }

 final Service other = (Service) obj;
 if (id == 0) {
 if (other.id != 0){
 return false;
 }
 } else if (!(id == other.id)){
 return false;
 }
 return true;
 }
