我想在 ExtJS 4.1 中创建一个 ItemSelector，但它们似乎没有两个列表的有效“标题”属性。这正是我想要的：
http://dev.sencha.com/deploy/ext-4.0.0/examples/multiselect/multiselect-demo.html
（注意两个标题：“available”和“selected”）
这是适用于 4.1 版本的“相同示例”：
http://dev.sencha.com/deploy/ext-4.1.0-gpl/examples/multiselect/multiselect-demo.html
这就是我下载 extJS 4.1 并从早期版本（4.0.7）添加 ItemSelector 和 MultiSelect 文件的原因。然后我复制了第一个示例中的几乎所有内容，但什么也没做，我也没有错误消息。
请告诉我我应该如何使这样的 ItemSelector 工作（最好使用 ext JS 4.1，因为它是最新版本，并且从不推荐使用的版本开始似乎是错误的，但在这一点上，任何可行的解决方案都可以，因为我用完了想法）。
这是我的html文件：

在此处插入标题
