列表视图getListItemXmlAttributes方法失败，并具有子发布项目
我已经创build了一个JS类来填充SG /文件夹列表视图数据，当项目被修改。 （ 按照Jaime的方法）当我操作创build出版物中的项目时，一切都很好。
例如：我打开一个组件或页面， locked by列locked by的自定义立即更新并显示我的用户名。
然而，当我去一个儿童出版物，并重复这个过程，我得到的窗口，问我是否要本地化或编辑父项。 如果我select编辑父窗口，代码不起作用。 我还没有完全想到它与初步debugging。 Chrome似乎吞噬了这个错误，Firefox给了我一个神秘的：

错误：未捕获exception：[exception…]组件返回失败代码：0x80004002（NS_NOINTERFACE）[nsIWebProgress.DOMWindow]“nsresult：”0x80004002（NS_NOINTERFACE）“位置：”JS框架:: chrome：// browser / content / tabbrowser .xml :: :: line 545“data：no]
有没有人有任何初步的想法？ 我会尽量后来发布一些代码…

[exception…]组件返回失败代码：0x80004002（NS_NOINTERFACE）[nsIWebProgress.DOMWindow]“
这意味着没有窗口分配给nsIWebProgress对象。 所以无处显示数据。
nsresult：“0x80004002（NS_NOINTERFACE）”location：“JS frame :: chrome：//browser/content/tabbrowser.xml :: :: line 545”data：no]
这是告诉你什么文件与该错误相关联。 以及它故障的线路。
但真正的关键是NS_NOINTERFACE错误。 这意味着界面尚未注册。
您正在使用Type.enableInterface() 。 这是一个自定义的方法，你在其他地方声明？ 我不明白 您可能想要将其更改为.registerInterface()
看到这个链接types类和Type.registerInterface（）
