      i'm using JBoss Seam too, but seems that that is not involved in the problem.
      my processdefinition is generated programatically, but should be similar that this:

      <?xml version="1.0" encoding="UTF-8"?>
      
      <process-definition xmlns="" name="SuperSt">
       <start-state name="start">
       <transition name="" to="super1"></transition>
       </start-state>
      
       <super-state name="super1">
       <transition name="" to="task2"></transition>
       <task-node name="task2">
       <task name="s" >
       <assignment actor-id="actorB" />
       </task>
       <transition name="" to="../end1"></transition>
       </task-node>
       </super-state>
      
       <end-state name="end1"></end-state>
      
      </process-definition>
      


      is this a problem with the superstates. i must use superstates that include task nodes inside, but i have many problems with that .
      Any ideas???
