    Lock problems after migrating to JBPM 3.2 and Seam 2.0

    Olivier Thierry Apprentice

      Hello,

      I had an application running on JBoss 4.0.5 with Seam 1.2.1 and JBpm 3.1. It had a business process with nodes configured as following :

      <node name="Envoi e-mail au déclarant">
       <transition to="Afficher RTT OK" />
       <action expression="#{demandeAbsenceAction.envoyerEmailDeclarant}" />
      </node>


      "demandeAbsenceAction" is a Seam component with processInstance injected. The method is as following :

      public void envoyerEmailDeclarant() throws Exception {
       log("Envoi d'un e-mail au déclarant !");
       processInstance.signal();
      }


      But a few days ago I migrated to Seam 2.0 and JBpm 3.2, running on JBoss 4.2. And I have now an error I don't understand, which is thrown on the "signal" call, with this stack trace :

      2007-09-19 12:23:57,465 ERROR [org.jbpm.graph.def.GraphElement] action threw exception: couldn't evaluate expression '#{demandeAbsenceAction.envoyerEmailDeclarant}'

      It talks about locked tokens, but I can't understand what it means. And overall I can't understand why I have this problem with JBpm 3.2, and not JBpm 3.1. Anyone has an idea ?

      Thanks in advance ;)
