      Hi!

      i have a strange error, i have an a4j:commandButton which triggers a server side action and should then refresh part of the page. well nothing special so far. the action is triggered and as far as the server side log and the debugger tell me, everything is normal, but the client is not refreshed and a4j:log has this entry:

      debug[11:51:26,088]: NEW AJAX REQUEST !!! with form :editAssociationInclude:editAssociationForm

      The source code is a bit complicated but the important things are: 
      <rich:modalPanel ..>
 <a4j:region..>
 <h:form..>
...
<a4j:outputPanel id="actionButtons" layout="block" ajaxRendered="true">

 <a4j:commandButton id="saveAssociationButton"
 value="#{messages['save']}"
 disabled="#{empty oneToManyAssociationTable.otherSideEntity}"
 action="#{oneToManyAssociationTable.onAcceptChanges()}"
 status="modalStatus"
 reRender="#{reRenderOnSave}"
 eventQueue="defaultQueue"
 <f:param name="conversationPropagation" value="join"/>
 </a4j:commandButton>
 </a4j:outputPanel>

 </h:form>
 </a4j:region>
</rich:modalPanel>


      I think there is nothing special to it, except perhaps that the button is reRendered to update its disabled state. The action method is called and returns (void).

      perhaps i should mention the server has this warning: 
      WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.


      So I dont know why the client gets no (useful??) response, I hope you have some hints on why this could occur.

      Thanks,
