rich:extendedDataTable selection inside a component

[jgromero]

Hi,

I have a composite component that shows a rich:popupPanel when a button is clicked. Then, inside the rich:popupPanel I perform a search, that is shown in a rich:extendedDataTable. So far, everything seems to work. Finally, I have to be able to double click one row in the table and the row double-clicked should be selected and rendered in the field's values of the component.

The problem is that when I double click, the first time the rich:popupPanel is correctly hidden, the bean is actually updated, but the fields in the component do not show the update. However, if I open again the rich:popupPanel, and selects the same row, the field's values of the component are updated and showed correctly.

Here I show the most relevant parts of source code:

The component:

{code:xml}
<composite:implementation>
     <a4j:region renderRegionOnly="true">
          <rich:panel header="${messages_emision['tomadores.titulo']}" id="panelTomador">
               <h:inputText id="nombres" readonly="#{!cc.attrs.esCotizacion}"
                         value="#{cc.attrs.tomador.nombres}"/>
               <a4j:commandLink execute="@this"
                         oncomplete="#{rich:component('buscarTerceroPanel')}.show()">
                    <img src="#{facesContext.externalContext.requestContextPath}/resources/images/find.png"
                              border="0" width="14" height="14" alt="Buscar"/>
               </a4j:commandLink>
          </rich:panel>
     </a4j:region>
     <rich:popupPanel header="${messages_emision['tercero.busqueda.titulo']}"
               id="buscarTerceroPanel" domElementAttachment="form" width="700" height="340">
          <a4j:outputPanel layout="block" id="panelBusqueda" ajaxRendered="true">
               <h:inputText id="documento" value="#{terceroMB.documento}"/>
               <a4j:commandButton id="siguiente" value="${messages['comun.buscar']}"
                         action="#{terceroMB.buscar}" execute="panelBusqueda" render="panelBusqueda"/>
               <rich:extendedDataTable value="#{terceroMB.listaTerceros}" var="terceroIter"
                         id="listaTerceros" selectionMode="single" selection="#{terceroMB.seleccionado}">
                    <a4j:ajax execute="@this" event="rowdblclick" render="panelTomador"
                              oncomplete="#{rich:component('buscarTerceroPanel')}.hide();"/>
                    <rich:column>
                         <f:facet name="header">${messages_emision['tercero.nombre']}</f:facet>
                         <h:outputText value="#{terceroIter.nombreCompleto}" />
                    </rich:column>
               </rich:extendedDataTable>
          </a4j:outputPanel>
     </rich:popupPanel>
</composite:implementation>
{code}

The bean:

{code:java}
@ViewScoped
@Named("terceroMB")
public class TerceroMB {
     private Tomadores tomador;
     public Object getSeleccionado() {
          if (seleccionado != null){
               Iterator<Integer> iterator = ((HashSet<Integer>)seleccionado).iterator();
               while (iterator.hasNext()){
                    Integer index = iterator.next();
                    tomador = (Tomadores) this.listaTerceros.get(index);
               }
          }
     }
...
}
{code}

I've search through the web, and performed several different approaches, but I didn't found the reason for this to happen.
