NEWUPDATE.JS

        {
            style: 'margin-top:3px',
            xtype: 'ueditor',
            id: 'newsContent',
            name: 'content',
            fieldLabel: '新闻内容',
            height: 270,
            allowBlank: false
        }]
});

添加没有问题。为什么setValue就有问题了？？求大神！！！！
补充：JSDUBUG value是有值的。但是 if (me.initialized) { 每次setValue 为false. 而且好像没有走 me.ueditorInstance.addListener('contentChange', function () {
alert(111);方法。
