我有一个 JSF 2.1 应用程序，使用 primefaces 3.4 开发，工作正常。当我将代理过滤器添加到我的 glassfish 3.1 服务器时出现问题。当我单击 glassfish 控制台中的按钮时，出现“无法将 AddRemoveListener 附加到 UIViewRoot，因为它为空”错误。有人遇到类似的问题吗？
web.xml
<filter>
<filter-name>Agent</filter-name>
<filter-class>com.sun.identity.agents.filter.AmAgentFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>Agent</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>INCLUDE</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>
Glassfish 控制台中的错误：
ATTENTION: Unable to attach AddRemoveListener to UIViewRoot because it is null
ATTENTION: StandardWrapperValve[Faces Servlet]: PWC1406: Servlet.service() for servlet Faces Servlet threw exception
java.lang.NullPointerException

在浏览器中
javax.servlet.ServletException: AmAgentFilter: An exception has occured
root cause
javax.servlet.ServletException: viewId:/clients.xhtml - La vue «/clients.xhtml» n?a pas pu être restaurée.
root cause
javax.faces.application.ViewExpiredException: viewId:/clients.xhtml - View "/ clients.xhtml" could not be restored.
我注意到，如果代理过滤器是这样的
<filter>
<filter-name>Agent</filter-name>
<filter-class> com.sun.identity.agents.filter.AmAgentFilter </filter-class>
</filter>
<filter-mapping>
<filter-name>Agent</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>INCLUDE</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>ERROR</dispatcher>
</filter-mapping>
（我删除 <dispatcher>REQUEST</dispatcher>）；我没有这个错误了。应用程序是否仍受此 OpenAm 过滤器配置保护？
