java.lang.UnsupportedOperationException,位于javax.faces.context.FacesContext.isReleasedFacesContext.java:609

问题描述

我正在集成SWF 2.2.1,Primefaces 2.2.1,JSF 2,Spring Security 3,Spring 3.1.0M1。 我能够访问Spring web-flow xml中提到的第一页,但出现以下错误。
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中只有很少的代码
<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>
