我搜索了很多网页谷歌和这里的Stack Overflow，但没有任何建议解决了我的问题。

I searched for many pages of the web through of the Google and here on the Stack Overflow, but nothing suggested resolved my problem.

经过多次尝试和踢后，我改变了测试控制器的方式。然后我发现问题一直发生在Chrome浏览器中我通过 Ctrl + Shift + T 快捷方式重新打开页面。所以页面运行了，但没有父窗口引用，因此无法关闭。

After many attempts and "kicks", I changed my way of to test that controller. Then I have discovered that the problem occurs always which I reopened the page through of the Ctrl + Shift + T shortcut in Chrome. So the page ran, but without a parent window reference, and because this can't be closed.
