我尝试运行RichFaces4应用，但组件无法渲染。例如，当我尝试这个演示：Demo我得到这样的东西：

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。

Answer 1

这就是Crome开发者工具告诉我http://img571.imageshack.us/i/rfnotdefined.jpg（未捕获的ReferenceError：RichFaces未定义）

这意味着生成的HTML <head>中未提供RichFaces所需的JavaScript文件。您需要确保在模板中使用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。

但我想知道服务器日志中是否记录了<h:head>的缺失。密切关注服务器日志。

Answer 2

至少在某些情况下，没有任何内容记录到服务器日志中缺少<h:head>。使用MyFaces 2.1.4的facelets模板中的<head>，WAS 7.0.0.13上的RichFaces 4.0.0会导致RichFaces组件无法正常呈现，但a4j组件工作正常。在迁移JSF1项目时，一定要注意什么。

RichFaces4不呈现组件
