spring - 为什么 RichFaces 4 组件无法正确渲染？

Question

我在 JBoss EAP 6.1 上使用 RichFaces 4 以及 JSF、Spring 和 Spring Web Flow，从 JBoss EAP 5.1 上的相应技术(例如 RichFaces 3.3)迁移而来。

问题在于 rich: 命名空间中的任何组件或控件都会为其生成一些 HTML，但当它在浏览器中呈现时，它看起来与 RichFaces 展示站点上的相应组件完全不同。似乎有 CSS 和图像文件应该与 RichFaces jar 文件捆绑在一起，但浏览器无法找到它们。下面的屏幕截图。 .

作为测试，我选择了一个简单的控件，即 rich:collapsiblePanel，并将展示网站中的示例代码粘贴到我们应用程序的测试页面中。可折叠面板出现，但看起来与演示网站上的面板完全不同。下面的屏幕截图。 .

我在多个浏览器(IE、Firefox 和 Chrome)和多个 rich: 组件(例如 rich:extendedDataTable、rich:tabPanel、rich:calendar)中得到相同的结果，所以我认为这指向一个库或配置问题。

我还查看了 this question和 this question这似乎是相关的，但我找不到任何信息来帮助解决我的问题。

有什么建议吗？

原来是 Spring 配置问题。如果您使用 Spring 和/或 Spring Web Flow，请检查配置文件中是否有以下代码。请注意，这些只是代码片段，而不是完整的配置文件。

webflow-config.xml
