listShuttle : can not get targetValue when submit

[xuantoan2510]

I tried to use listShuttle but I can not get targetValue from my Bean on server.Help me do this. Thanks

my page

 <h:form>
 <rich:listShuttle sourceValue="#{capitalsBean.capitals}" targetValue="#{capitalsBean.capitals2}" var="cap" converter="converter">
 <rich:column>
 <h:outputText value="#{cap.name}"/>
 </rich:column>
 </rich:listShuttle>
 <rich:dataTable value="#{capitalsBean.capitals2}" var="list" id="table">
 <rich:column>
 <h:outputText value="#{list.name}"/>
 </rich:column>
 </rich:dataTable>
 <h:commandButton value="store"/>
 </h:form>

capitalsBean:

private List<Capital> capitals2 = new ArrayList<Capital>();
 private ArrayList<Capital> capitals = new ArrayList<Capital>();
...
///initialization
// getters , setters

Capital:

package demo.table;

import java.io.Serializable;

public class Capital implements Serializable {
 /**
 *
 */
 private String name;
 private String state;

 public Capital() {
 }

 public Capital(String name, String state) {
 setName(name);
 setState(state);
 }

 public String getName() {
 System.out.println(name);
 return name;
 }
 public void setName(String name) {
 this.name = name;
 }
 public String getState() {
 return state;
 }
 public void setState(String state) {
 this.state = state;
 }

 @Override
 public int hashCode() {
 final int prime = 31;
 int result = 1;
 result = prime * result + ((name == null) ? 0 : name.hashCode());
 result = prime * result + ((state == null) ? 0 : state.hashCode());
 return result;
 }

 @Override
 public boolean equals(Object obj) {
 if (this == obj)
 return true;
 if (obj == null)
 return false;
 if (getClass() != obj.getClass())
 return false;
 final Capital other = (Capital) obj;
 if (name == null) {
 if (other.name != null)
 return false;
 } else if (!name.equals(other.name))
 return false;
 if (state == null) {
 if (other.state != null)
 return false;
 } else if (!state.equals(other.state))
 return false;
 return true;
 }
}

And the converter

package demo.table;

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

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

 public Converter() {
 }

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

 int index = value.indexOf(':');

 return new Capital(value.substring(0, index), value.substring(index + 1));
 }

 public String getAsString(FacesContext context, UIComponent component,
 Object value) {
 Capital optionItem = (Capital) value;
 return optionItem.getName() + ":" + optionItem.getState();
 }

}

so, in this simple example - I duplicate values from target lsit to dataTable.

Also check demosite examlpe from SVN to look through the example more closer.

i want to get targetValue in actionSave method. Do you suggest?

[xuantoan2510]

I test successfully with sample and i think that two methods equals and hashCode of property are very important. Thanks
