in browser

javax.servlet.servletexception: amagentfilter: 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" not restored.

i notice that,if agent filter 

<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>

(i remove <dispatcher>request</dispatcher> ); don't have error anymore. application still protected openam filter configuration?

i've seen same error (warning: unable attach addremovelistener uiviewroot because null) in few rare cases while debugging. particulars had browser window open previous debugging run attempting ajax callback on timer. had recompiled app in interim (with netbeans) , re-run it. every time browser non-current tab issued ajax call saw warning.
