我们正在将JSF 1.1(MyFaces)项目迁移到JSF 2.我们的想法是通过将JSP和XHTML保持在一起一段时间来定期迁移.我们在JSP页面中使用了许多ajax4jsf-1.1.1标记.我们不使用RichFaces.将系统配置为JSF 2(Balusc教程中提到的所有配置更改)当尝试在类路径中使用ajax4jsf.jar访问JSP页面时,我们得到一个异常:

Caused by: java.lang.IllegalStateException: setViewHandler may not be executed after a lifecycle request has been completed
    at org.apache.myfaces.application.ApplicationImpl.setViewHandler(ApplicationImpl.java:853)
    at org.ajax4jsf.framework.ajax.InitPhaseListener.beforePhase(InitPhaseListener.java:92)
    at org.apache.myfaces.lifecycle.PhaseListenerManager.informPhaseListenersBefore(PhaseListenerManager.java:76)
    at org.apache.myfaces.lifecycle.LifecycleImpl.executePhase(LifecycleImpl.java:131)

它看起来ajax4jsf.jar与JSF 2不兼容.看起来LifeCycle配置存在一些问题.

有没有什么办法可以让a4j与JSF 2 JSP一起工作？我知道当我们使用XHTML时,我们不需要这一切.

我在登录页面上收到以下错误.在呈现响应后非法尝试设置ViewHandler.

我正在使用Richfaces 3.3.3和facelets以及jsf和tomcat
