APAR status

• Closed as program error.

Error description

• Multi-window usage with server-side state saving is broken and
  throws a javax.faces.application.ViewExpiredException:
  
  The fix is similiar to the one that has been addressed in
  myfaces-3117
  
  The following exception is observed.
  Exception:
  #####
  javax.faces.application.ViewExpiredException:
  /entity/search/entitySearch.xhtmlNo saved view state could be
  found for
  the view identifier: /entity/search/abc.xhtml

Local fix

• Work around where we set the JSF State to  client
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:  IBM WebSphere Application Server Full       *
  *                  Profile versions 8.0 and 8.5.5 and Liberty  *
  *                  Profile version 8.5.5 users of JavaServer   *
  *                  Faces (JSF) MyFaces                         *
  ****************************************************************
  * PROBLEM DESCRIPTION: A ViewExpiredException can occur in a   *
  *                      multi-window scenario when using JSF.   *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The viewstate stored in a session will be overwritten when the
  number of viewstates stored exceeds the number of views
  specified by the context parameter
  org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION (20 by default).
  When multiple windows are in use, this can lead to a
  viewstate loss if a particular window's viewstate is
  overwritten by another window's saved viewstates.
  A stack trace like the one shown below might be observed when
  this defect is present:
  javax.faces.application.ViewExpiredException: /xxx.jsf
  No saved view state could be found for the view identifier:
  /xxx.jsf

  org.apache.myfaces.lifecycle.RestoreViewExecutor.execute(Restore

  eImpl.java:172)
  at
  org.apache.myfaces.lifecycle.LifecycleImpl.execute(LifecycleImpl
  .java:119)
  ...
  

Problem conclusion

• The JSF MyFaces code was updated to avoid the problem when the
  following context parameter is set to true:
  com.ibm.ws.jsf.enableRemoveRestoredViewState
  (true/false - default).
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.0.0.10 and 8.5.5.5.  Please refer to the
  Recommended Updates page for delivery information:
  http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
  

Temporary fix

• Setting the context parameter javax.faces.STATE_SAVING_METHOD
  = client (server - default/client) resolves this issue but
  also increases network bandwidth usage.
