我的代码与演示中的代码几乎相同。我刚刚添加了表单标签，因为它抱怨它。
My code is almost the same as in the demo. I just added form tag becouse it complained for it.

推荐答案
那是什么Crome开发者工具告诉我 http://img571.imageshack.us/i/rfnotdefined.jpg（未捕获的ReferenceError：未定义RichFaces）
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RichFaces的必要JavaScript文件未被删除在生成的HTML < head> 中提供。您需要确保使用JSF < h：head> 组件而不是纯HTML < head> 。这就是新的JSF 2.0资源注入机制的mandatroy，JSF和RichFaces将在那里注入与Ajax / UI相关的JavaScripts / Stylesheets。
This means that the necessary JavaScript files of RichFaces are not been supplied in the generated HTML <head>. You need to ensure that you're using the JSF <h:head> component instead of plain HTML <head> in the template. This is namely mandatroy for the new JSF 2.0 resource injection mechanism, JSF and RichFaces will inject Ajax/UI-related JavaScripts/Stylesheets in there.
我不知道是否有任何东西已在服务器日志中记录缺少< h：head> 。密切关注服务器日志。
I however wonder if anything has been logged in the server log about the lack of the <h:head>. Keep an eye on the server logs.
