[jboss-user] [JBoss Portal] - Portal event and ViewExpiredException

[jaro777]

Hello,

  I got following issue.

Environment: 
  jboss-portal-2.7.0.GA (bundled version) -> JSF RI 1.2_08 and Jboss portlet bridge 1.0.0.B4

I have PortletA and PortletB - both are JSF portlets. PortletA publishes Event and PortletB processes it. Sometimes when event is triggered from PortletA, ViewExpiredException is thrown during restoring view of PortletB


  | Caused by: javax.faces.application.ViewExpiredException: viewId:/scsearch/scsearchdetail.jsp - View /scsearch/scsearchdetail.jsp could not be restored.
  | 	at com.sun.faces.lifecycle.RestoreViewPhase.execute(RestoreViewPhase.java:186)
  | 	at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:100)
  | 	at com.sun.faces.lifecycle.RestoreViewPhase.doPhase(RestoreViewPhase.java:104)
  | 	at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:118)
  | 	at org.jboss.portletbridge.AjaxPortletBridge.execute(AjaxPortletBridge.java:587)
  | 	at org.jboss.portletbridge.AjaxPortletBridge.renderResponse(AjaxPortletBridge.java:441)
  | 	at org.jboss.portletbridge.AjaxPortletBridge.doFacesRequest(AjaxPortletBridge.java:344)

As workaround this partly works (at least stack trace is not displayed though event is not processed) - add it to web.xml of PortletB's war

  | <context-param>
  | 	<param-name>com.sun.faces.enableRestoreView11Compatibility</param-name> 
  |         <param-value>true</param-value>
  | 

Still not satisfied with "solution" I debug JSF and came to strange conclusion: JSF adds hidden field into form (there is form in both PortletA and PortletB underlying jsp page) like 


  | <INPUT id="javax.faces.ViewState" type="hidden" name="javax.faces.ViewState" value="j_id9" />  w
  | 	</context-param> 
  | 

This values stores version of view stored in session for particular view. Problem is that the same version is used for both portlets - in case that PortletB does have such a version (e.g. html would like like)



  | <INPUT id="javax.faces.ViewState" type="hidden" name="javax.faces.ViewState" value="j_id8" />  w
  | 	</context-param> 
  | 

than no view is found and ViewExpiredException is thrown.

Any idea how to solve this properly?

Thanks
Jaro
