Any update on this issue, i am facing an issue somewhat related, where
clicking on an ajaxlink once the session expiry has reached, gives a
nullpointer exception at
BookmarkableListenerInterfaceRequestTarget.processEvents ...(Below is the
exception stack-trace), btw i am using QueryStringUrlCodingStrategy url
coding strategy to mount the pages....The behavior is fine for non-ajax
component, where i am taken to the session-expiry page...
Thanks in advance..
