JSP kendo grid EDIT /ADD Handle ERROR response from spring rest Kendo UI v2015.3.1111

Question

尝试 Kendo UI JSP 可编辑网格。网格正在解决一些问题。 （版本：剑道UI v2015.3.1111）

1. 导出：即使使用 allPages="allPages"，它也只能导出当前
   页面。
2. 创建后，GRID 不会更新为具有用户 createDate 的服务器响应。与更新相同，网格未随更新日期更新 即使传递了更新的用户对象。
3. 网格显示添加的用户，即使它在后端失败。如何处理创建/更新的错误响应并显示失败消息？

非常感谢任何帮助。

控制器创建部分：

    @RequestMapping(value = "/user/create", method = RequestMethod.POST)
    public @ResponseBody User create(@RequestBody Map<String, Object> model) {
        log.debug("create");
        User target = new User();

        target.setUserName((String)model.get("UserName"));
        target.setFirstName((String)model.get("firstName"));
        target.setLastName((String)model.get("lastName"));
        target.setOpenDate(getDateFromStr((String)model.get("openDate")));
        target.setEditDate(getDateFromStr((String)model.get("editDate")));
        User user = userDao.createUser(target);
        log.info("user"+user.getUserId()+user.getOpenDate());
        return user;
    }

JSP 部分：

<c:url value="/user/destroy" var="destroyUrl" />

自己解决了：对于 pdf，allPages="true" 有效。

网格刷新：FOR requestEnd 事件

    function onRequestEnd(e) {
      if (e.type == "create") {
            e.sender.read();
      }
      else if (e.type == "update") {
            e.sender.read();
      }
   }
