    Lewis Florez Newbie

      I have the following xhtml code

      <ui:composition xmlns="http://www.w3.org/1999/xhtml

                      </a4j:form>
                     
              </ui:define> 
      </ui:composition> 

      but I have the following error when time is called,
      <a4j:poll id="po" interval="240000" ajaxSingle="true" limitToList="true" action="#{chat.desconectar()}" reRender="po,users" />

      provides an exception

      Exception during request processing:
      Caused by javax.servlet.ServletException with message: "#{chat.desconectar()}: java.lang.IllegalArgumentException: id to load is required for loading"

      help me??
