Hello

I have this xml:

<rich:dataTable value="#{AddServiceWizard.service.processList}"
                        var="process"
                        style="width: 100%;"
                        noDataLabel="Нет данных">
            <f:facet name="header">
                <rich:columnGroup>
                    <rich:column colspan="2">
                        Процессы и используемые порты (#{AddServiceWizard.service.processList.size()})
                        <h:graphicImage value="/resources/images/edit.gif" 
                                        title="Изменить" 
                                        style="vertical-align: bottom;float:right;cursor: pointer"
                                        onclick="$('#details').slideUp(700);$('#addProcessDiv').slideDown(700)"/>
                    </rich:column>
                </rich:columnGroup>
            </f:facet>
            <rich:column colspan="2">
                <rich:collapsibleSubTableToggler for="portsSubtbl"/>
                <h:outputText value="#{process.processRef.processName} (Портов - #{process.portsList.size()})" style="font-weight: bold;"/>                        
            </rich:column>
            <rich:collapsibleSubTable value="#{process.portsList}" 
                                      id="portsSubtbl" 
                                      var="port" 
                                      expandMode="client"
                                      expanded="false"
                                      noDataLabel="Порты не зарегистрированы">
                <rich:column>
                    <f:facet name="header">
                        Протокол
                    </f:facet>
                    #{port.protocol.protocolName}
                </rich:column>
                <rich:column>
                    <f:facet name="header">
                        Номер порта
                    </f:facet>
                    #{port.portNumber}
                </rich:column>
            </rich:collapsibleSubTable>
        </rich:dataTable>

Problem is that expanded attribute of collapsiblesubtable doesn't work at all, with or without headers in subtable's columns

Is there any solution to overcome the problem?
