Problem with f:ajax , setters not called

Question

Hi,
I have this jsf
<ui:define name="content">
<h:form>
<h:selectOneRadio value="#{chargeMenuBacking.inputMethod}">
<f:selectItem itemValue="#{chargeMenuBacking.COMMUNITY}" itemLabel="Community" />
<f:selectItem itemValue="#{chargeMenuBacking.FILE}" itemLabel="File" />
<f:ajax event="click" render="myGroup" />
</h:selectOneRadio>
<h:panelGroup id="myGroup">
<h:panelGroup id="CommunityGroup" rendered="#{chargeMenuBacking.inputMethod==chargeMenuBacking.COMMUNITY}">
<h:selectManyListbox value="#{chargeMenuBacking.communitiesSelections}">
<f:selectItems value="#{chargeMenuBacking.communities}" var="u" itemValue="#{u.id}" itemLabel="#{u.name}"/>
</h:selectManyListbox>
</h:panelGroup>
<h:panelGroup id="FileGroup" rendered="#{chargeMenuBacking.inputMethod==chargeMenuBacking.FILE}">
<h:inputText value="#{chargeMenuBacking.filename}" />
</h:panelGroup>
</h:panelGroup>
<h:commandButton value="OK" action="#{chargeMenuBacking.doCharge}"/>
<h:commandButton value="Cancel" action="#{chargeMenuBacking.doCancel}"/>
</h:form>
</ui:define>
and I have this backing bean
@Named(value = "chargeMenuBacking")
@RequestScoped
public class ChargeMenu implements Serializable ... (blah blah)
When the bean is RequestScoped the setter for chargeMenuBacking.communitiesSelections is not called.
However if the bean is SessionScoped or if I do not use the <f:ajax> tag (thus always rendering the component) the setter is called.
Do you have any ideas why this is happening?
I am using Glassfish v3 with netbeans 6.9.1 and JSF 2.0

Answer 1

The solution seams to be declaring the bean as having view scope.
