I’m just guessing here, but you could try to remove the error handling part for the ViewExpiredException from the web.xml and check if this helps.
If this doesn’t help, you will have to debug the cause. At some point during request processing HttpServletReponse.isCommitted() switches from false to true. This is the cause for the exception.
You could also try to remove all mappings from your pretty-config.xml to see if the exception still occurs.
