我正在使用Selenium Webdriver - 页面对象模型与Page Factory进行自动化。
问题：点击提交控件后停留在同一页面上并且不加载下一页，因为我在下一页检查的元素显示为代理元素。
问题： 我的代码中有什么不对吗？ 我没有等待元素出现的时间吗？ 我在UberDashboard上使用了错误的定位器吗？ - 我最初使用div classname，但firebug无法使用它找到元素，因此切换到span（span.user-name-display），它与firebug一起工作正常。
我在stackoverflow上发现了很多问题，并参考了许多关于页面工厂的教程和博客，我发现我的代码没有任何不正确之处，但是一双新的眼睛可能指向我错过的东西。
非常感谢有关如何解决此问题的任何指示。
