我尝试运行 RichFaces4 应用程序，但组件未呈现。例如，当我尝试这个演示时:Demo我得到这样的东西:
Here is an example of default tab panel with 3 tabs.

Here is tab #3
我的代码与演示中的代码几乎相同。我只是添加了表单标签，因为它提示它。

最佳答案
That's what Crome Developer Tools told me http://img571.imageshack.us/i/rfnotdefined.jpg (Uncaught ReferenceError: RichFaces is not defined)
这意味着生成的 HTML 中未提供必要的 RichFaces JavaScript 文件 <head> .您需要确保您使用的是 JSF <h:head> 组件而不是纯 HTML <head>在模板中。这就是新的 JSF 2.0 资源注入(inject)机制的强制要求，JSF 和 RichFaces 将在其中注入(inject)与 Ajax/UI 相关的 JavaScripts/样式表。
但是我想知道服务器日志中是否记录了关于缺少 <h:head> 的任何信息.密切关注服务器日志。
