Hi all,

I want to use the new <rich:comboBox> for my application, but I'm facing some problems that the backing bean value is lost after the second refresh of an area ...

I have the following example page:

<h:form id="test">
 <rich:panel id="orderHead">
 <a4j:commandButton id="com" reRender="part" action="#{suggest.setProp2}" value="Refresh"/>
 <rich:panel id="part">
 <rich:comboBox value="#{suggest.property}">
 <f:selectItems value="#{suggest.comboSelectItems}" />
 </rich:comboBox>
 <h:outputText id="propOut" value="#{suggest.property}" /><br/>
 <h:outputText id="propOut2" value="#{suggest.property2}" /><br/>
 </rich:panel>
 </rich:panel>
</h:form>

With the following backing bean code:

import java.util.Date;
import javax.faces.model.SelectItem;

/**
 * Test bean for rich:comboBox
 *
 */
public class SuggestBean {

 // Property bind to the combo box
 private String property;
 // Property to verify re-rendering
 private String property2;

 private SelectItem[] comboSelectItems = { new SelectItem("Test", "Test"), new SelectItem("Test2", "Test2"), new SelectItem("Test3", "Test3") };

 /**
 * Updates property2 with current date.
 */
 public void updateProperty2() {
 // Only to verify the re-rendering is done
 setProperty2((new Date()).toString());
 }

 public String getProperty() {
 return property;
 }

 public void setProperty(String property) {
 this.property = property;
 }

 public String getProperty2() {
 return property2;
 }

 public void setProperty2(String property2) {
 this.property2 = property2;
 }

 public SelectItem[] getComboSelectItems() {
 return comboSelectItems;
 }

 public void setComboSelectItems(SelectItem[] comboSelectItems) {
 this.comboSelectItems = comboSelectItems;
 }

}

The bean has two properties, one is bound as value to the combo box, the other property is updated with the current date if updateProperty2() method is called.

If I press the "refresh" button for the first time, everything is fine (poperty2 is updated with the current date, property 1 contains my comboBox selection). If I press the button again, the date is updated but the property value is removed (from comboBox and h:outputText!).

Am I doing something wrong or is it a but? Unfortunately there is no example in the demo application where a backing bean value is bind to a combo box!

Thanks & Regards
