    JBPM and SEAM

    Roland Wiesemann Newbie

      Hi,
      i'm using JBoss AS 4.2.2 with java 1.6.07.

      I have an application A.ear including JBPM. If i deploy this application alone, it works fine.
      Than i have an application B.war including SEAM. This application has no relations to the application A.ear. If i deploy the application B.war alone, it works fine.

      If i deploy the applications A.ear and B.war together, the first application A.ear throws following Exception by evaluating the expression '#{context.transitionValidateFlight}'.

      It is fixed by restarting JBoss, without the application B.war.

      Anyone can help?
      How can i preserve the application A.ear from the SeamExpressionEvaluator? used in application B.war (in the event that is the problem)
