javax.faces.context.FacesContext.isReleased(FacesContext.java:609)中的java.lang.UnsupportedOperationException

Question

我正在集成SWF 2.2.1,Primefaces 2.2.1,JSF 2,Spring Security 3,Spring 3.1.0M1.我能够点击Spring web-flow xml中提到的第一页,但是出现了以下错误.

com.sun.faces.application.view.FaceletViewHandlingStrategy handleRenderException
SEVERE: Error Rendering View[/WEB-INF/flows/AccSrch/searchAccIns.xhtml]

令我惊讶的是,我的.xhtml中只有最少的代码

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
   xmlns:ui="http://java.sun.com/jsf/facelets"
   xmlns:h="http://java.sun.com/jsf/html"
   xmlns:f="http://java.sun.com/jsf/core"
   xmlns:p="http://primefaces.prime.com.tr/ui">
   <ui:define name="content">
      <f:view>
         <h:form id="expire" prependId="false">
            <h:outputText value="HEllo" />
         </h:form>
      </f:view>
   </ui:define>
</ui:composition>

一些事实:

• 根据您在其他问题中的堆栈跟踪中Tomcat特定类的外观,您正在使用Tomcat.
• 根据FacesContext#isReleased()当前问题中stacktrace中JSF 2.1引入方法的外观,您使用的是JSF 2.1.
• 根据你的另一个问题的答案,你可能正在使用Mojarra 2.1.0.
• Mojarra 2.1.0 在Tomcat/Jetty中不起作用,因为在未附带内置注释扫描器的容器的注释扫描实现中意外引入Glassfish特定代码的主要错误.

因此,要解决这个问题,有几种选择:

• 降级至Mojarra 2.0.5.
• 升级到Mojarra 2.1.1.
• 用Glassfish 3,JBoss AS 6或其他东西替换Tomcat.
