java - 渲染icefaces 2视图期间的java.lang.StackOverflowError

Question

我做了一个 Icefaces 1.8 升级到 2.0 版本。我知道有些人会告诉我为什么版本是 2.0 而不是 3.0，我很想但我别无选择。由于映射 Faces Servlet，我们遇到了问题。我们有以 exetension .jspx 结尾的 JSP 文件，因此我们添加了一个 url 模式来管理它们。页面的渲染我们有一个stackoverflow，因为我认为有一个无限循环。

使用 url-pattern=*.jspx 我有一个 stackoverflow
使用 url-pattern=/icefaces/* 我有一个 NullPointerException 因为 FacesContext 为空。

堆栈跟踪
