我新增了一天数据，然后点击修改按钮，页面跳转为空白，看日志就报上面的错误。

表没有id字段？

@wendal 有的 已经新增成功一条，而且 如果我把 页面的id删了，之后字段也会报错。

看了下代码生成器生成的edit没有返回值，直接把值放到了 我看 


@At("/edit/?")
    @Ok("beetl:/platform/course/course/type/edit.html")
    @RequiresPermissions("platform.course.course.type")
    public void edit(String id,HttpServletRequest req) {
		req.setAttribute("obj", powzCourseTypeService.fetch(id));
		log.info("obj"+req.getAttribute("obj"));
    }

cms模块的修改代码 返回的是object

 @At("/edit/?")
    @Ok("beetl:/platform/sys/dict/edit.html")
    @RequiresPermissions("sys.manager.dict")
    public Object edit(String id, HttpServletRequest req) {
        Sys_dict dict = dictService.fetch(id);
        if (dict != null) {
            req.setAttribute("parentUnit", dictService.fetch(dict.getParentId()));
        }
        return dict;
    }

你改返回值干毛线

方法的返回值就会设置到req的attr，名字就叫obj

@wendal 我没有改，下面的那个改了的是系统自带的，上面的那个obj的是代码生成器生成的。

我跟楼主一样的问题哎，用代码生成器生成的代码，进edit和detail就报ATTRIBUTE_NOT_FOUND的错误

已解决，lombok用习惯了，model类没有添加getter/setter的缘故。
