datalist not rerendered on ajax action

[troubadur]

I have a datalist within an a4j:region which contains a list of names. At page laoding the names are correctly printed.

By selecting one Name of the Selectbox (which is also within the region) i want to add this selected Name to be printed out at the dataList.

Here is my xhtml-snippet:

<a4j:region id="names_region" renderRegionOnly="true" >
     <rich:dataList styleClass="inlinelist" id="name_repeat" value="#{personDetailBean.names}" var="name"  >
          <h:outputText value="#{name.fullName}" />
     </rich:dataList>
                    
     <h:selectOneListbox  id="new_name" size="1" value="#{personDetailBean.currentName}" >
          <a4j:support actionListener="#{personController.addName}" event="onchange" />
          <f:selectItems value="#{utilWebController.namesForSelect }"/>
          <f:converter converterId="nameConverter"/>
     </h:selectOneListbox>
</a4j:region>

The actionlistener which is initiated by the onchange-event looks like this:

public void addName(ActionEvent event) {
     PersonDetailBean detailBean = (PersonDetailBean) getRequestBean(RequestBeanName.PERSON_DETAIL);
        
     Name name = detailBean.getCurrentName();

     detailBean.getNames().add(name);
     detailBean.setCurrentName(null);
}

When i debug into the request, i can see the method 'addName' is successfully called and processed and even the List of names increases with every ajax-request. However, the datalist does not update.

I'm using Richfaces 3.3.3.Final with JSF 1.2 (Myfaces) and Facelets.

i'm not exactly sure how, but somehow i made it work. What i did: I added the ajaxSingle="true" and reRender Attribute to the a4j:support-tag
