Custom sorting on a extended datatable is not working well. With a extended data table configured with this layout:

{code:xml}
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:a4j="http://richfaces.org/a4j"
      xmlns:rich="http://richfaces.org/rich">
    <h:head>
        <title>Titulo</title>
    </h:head>
    <h:body>
        <h:form>
            <h:panelGrid cellpadding="5" cellspacing="5" columns="4" width="100%">
                <f:facet name="footer">
                    <h:panelGrid cellspacing="10" columns="2" width="80%">
                        <a4j:commandButton actionListener="#{consultaFactibilidad.consultarDocumentos}"
                                           execute="this"
                                           render="documentos" 
                                           value="Buscar"
                                           styleClass="boton"/>
                    </h:panelGrid>
                </f:facet>
            </h:panelGrid>
            <rich:extendedDataTable var="documento"
                                    value="#{consultaFactibilidad.documentos}"
                                    id="documentos">
                <rich:column id="formato" width="200px"
                             sortBy="#{documento.formato.nombreCalificado}"
                             sortType="custom" sortOrder="#{controlOrdenTablas.orden}">
                    <f:facet name="header">
                        <a4j:commandLink execute="@this"
                                         action="#{controlOrdenTablas.ordenar}"
                                         render="documentos">
                            <h:outputLabel value="Formato" />
                        </a4j:commandLink>
                    </f:facet>
                    <h:outputText value="#{documento.formato.nombreCalificado}"/>
                </rich:column>
            </rich:extendedDataTable>
        </h:form>
    </h:body>
</html>{code}

When the user clicks on the link for the only column on the table the table sorts correctly ONLY the first time, the next click simply doesn't sort the data. No error messages on the server log, no error messages on a a4j:log either. The next time stops working completely. This only happens after the value collection is retrieved on the action listener {code}#{consultaFactibilidad.consultarDocumentos}{code} is called. When the data is retrieved before the page load, say on the postconstruct event listener on the backing bean, then the sort works correctly all times. Finally this ONLY happens with the extended datatable. It doesn't happen with a simple datatable.
