报错：Uncaught Error: Ext.Loader is not enabled, so dependencies cannot be resolved dynamically. Missing required class: Ext.data.Mode

当我把这句 Ext.Loader.setConfig({ enabled: true }); 加上
报Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:2134/data/Mode.js?_dc=1351584112203和Uncaught TypeError: Object #<Object> has no method 'read'

不知是不是缺少 Ext.Loader.setPath('Ext.ux', '@Url.Content("~/Scripts/Ext/ux")'); 这样的设置，如果是的话，@Url.Content("~/Scripts/Ext/ux")这个目录里面应该放那些文件

Ext.data下面没有Mode，是Model。。。

JScript code

            Ext.define('NewContent', {                //extend: 'Ext.data.Mode',                  extend: 'Ext.data.Model',                fields:                [                'NewsCategoryID',                'PublicDate',                'NewsMainTitle',                 'NewsSubTitle',                'NewsSummary',                'NewsListImage',                 'NewsContent',                'IsFocusNews',                'FocusNewsImage',                 'IsAllowComment',                'IsPublicToMobileClient',                'NewsStatus',                'CreateDatetime'                ]            });

ux文件夹一般放的是自定义的插件，如果Ext.require需要到ux文件夹下的控件，需要设置ux路径
JScript code
        Ext.Loader.setConfig({            enabled: true        });        Ext.Loader.setPath('Ext.ux', '../ux');
