JSF // Primefaces //按钮不显示.. apple vs windows？

Question

我有一个mysteroius问题。我的同学和我正在使用组件java面对eclipse中的项目进行编程，tomcat V9，mySQL，eclipse java EE。所以一切都很好，因为我们将视图转换为primefaces和css布局。我的队友（在苹果电脑上工作）可以毫无问题地运行项目。在我们的登录页面上，他们看到用户名+密码的按钮。当我运行login.xhtml时，我看到他们的css-layout使用我们的注销按钮和welcome-header，但是我看不到commandbuttons（用户名和密码）。我正在使用Windows PC，并安装了所有组件。好吧，我必须包含比他们更多的JARS（javax.faces-2.2.8，jstl-1.2，mysql-connector，primefaces-6.0），但在过去，所有的工作都是一样的。 在标记视图（eclipse）中是no问题显示，在控制台中有很多信息标签和一些警告，但似乎也有一切正常。 所以，我怎么能帮助你，你能解决我的问题的信息：对

这是我的控制台输出：

有这么多的可能性，这是一个有点势不可挡，以帮助建设性。 有迹象表明，这个问题可以从以下未来三大领域： 1）的Mac与Windows的 2）浏览器的差异（即,. IE，Safari浏览器，浏览器，Firefox） 3）应用状态/会话

它很可能是应用程序状态/会话。
