    Exceptions handling - strange behaviour of SeamFilter

    Przemyslaw Jaskierski Newbie

      After adding SeamFilter to my web.xml I'm getting error shown on stacktrace below. Problem appears in case of any application exception that appears after ajax4jsf's call that I'm performing with <a4j:commandLink/>.
