List view getListItemXmlAttributes method fails with child publication items
提问by Warner Soditus
I have created a JS class to populate SG/Folder list view data, when items are modified. (As per Jaime's approach)Everything works great when I operate on items in the publication they're created in.
我创建了一个 JS 类来在修改项目时填充 SG/文件夹列表视图数据。（按照 Jaime 的方法）当我对创建它们的出版物中的项目进行操作时，一切都很好。
Ex:I open a component or page and the custom locked bycolumn immediately updates and shows my user name.
例如：我打开一个组件或页面，自定义locked by列立即更新并显示我的用户名。
However, when I go to a child publication and repeat that process, I get the window asking if I want to localize or edit the parent item. If I select to edit the parent window, the code doesn't work. I haven't quite figured it out yet with initial debugging. Chrome seems to swallow the error, Firefox gives me a cryptic:
但是，当我转到子出版物并重复该过程时，会出现询问是否要本地化或编辑父项的窗口。如果我选择编辑父窗口，代码将不起作用。我还没有完全弄清楚初始调试。Chrome 似乎吞下了错误，Firefox 给了我一个神秘的：

[Exception... "Component returned failure code: 0x80004002 (NS_NOINTERFACE) [nsIWebProgress.DOMWindow]"
[异常...“组件返回失败代码：0x80004002（NS_NOINTERFACE）[nsIWebProgress.DOMWindow]”
This means that there was no window assigned to the nsIWebProgressobject. So it has nowhere to display data.
这意味着没有分配给nsIWebProgress对象的窗口。所以它无处可显示数据。
nsresult: "0x80004002 (NS_NOINTERFACE)" location: "JS frame :: chrome://browser/content/tabbrowser.xml :: :: line 545" data: no]
nsresult: "0x80004002 (NS_NOINTERFACE)" location: "JS frame :: chrome://browser/content/tabbrowser.xml :: :: line 545" data: no]
This is telling you what file is associated with that error. and what line it faulted on.
这告诉您与该错误相关联的文件。以及它在哪条线上出错。
But the real key is the NS_NOINTERFACE error. Which means the interface has not been registered.
但真正的关键是 NS_NOINTERFACE 错误。这意味着该接口尚未注册。
You are using Type.enableInterface(). Is that a custom method you are declaring somewhere else ? I don't see it. You might want to change that to .registerInterface()
您正在使用Type.enableInterface(). 这是您在其他地方声明的自定义方法吗？我没有看到。你可能想把它改成.registerInterface()
See this link Type Classand Type.registerInterface()
