我的bean类行编辑方法

     public void onEdit(RowEditEvent event)
     {
     System.out.println("onEdit methode of facility bean class");
    Facility facility=(Facility) event.getObject();
    facilityService.editFacilityList(facility);
       }
     myservice class editfacility method
    public void editFacilityList(Facility facility)
     {
           int userIdVal = (Integer) httpSession.getAttribute(Constants.USER_ID);
   facility.setUpdateUserId(userIdVal);    
    facility.setUpdateDate(new Date());
    facilityDao.attachDirty(facility);
