   {
      AsyncResponse response = takeAsyncResponse(stage);
      boolean ret = response.cancel();

      ret &= response.cancel();
      System.out.println("*** response.cancel() 2 " + ret);

      return b ? TRUE : FALSE;
   }
   
     protected static AsyncResponse takeAsyncResponse(String stageId)
