[jboss-user] [JBoss jBPM] - Task Assignement

[mailinator]

Hi,

i'm trying to assign a task to someome using swinlane and assignement handler.

My process definition :
<process-definition name=Acces>
   <swimlane name=RH>
      <assignment class=a.b.responsable.assignement.RhAssignementHandler config-type=constructor>     
      
   
<start-state name=Dem>
      <transition name=TDemRec to=SearchUti>
   </start-state>
   <task-node name=SearchUti>
      <task name=SearchUti>
         <assignment class=com.it.application.responsable.assignement.RhAssignementHandler config-type=constructor>
      
      <transition name=TSeaTyp to=STypeDem>
   </task-node>

My assignement handler :

public void assign(Assignable assignable, ExecutionContext executionContext) throws Exception {
TaskInstance task = executionContext.getTaskInstance();
task.setActorId(responsable.getId());
}

My problem is that i have this exception :

javax.servlet.ServletException: org.jbpm.graph.def.DelegationException
	org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:523)
	org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:421)

caused by :

org.jbpm.graph.def.DelegationException
	org.jbpm.taskmgmt.exe.TaskMgmtInstance.performAssignment(TaskMgmtInstance.java:214)
	org.jbpm.taskmgmt.exe.TaskInstance.assign(TaskInstance.java:199)

	org.jbpm.graph.node.TaskNode.execute(TaskNode.java:168)
	org.jbpm.graph.def.Node.enter(Node.java:318)

caused by :

java.lang.NullPointerException
	org.jbpm.taskmgmt.exe.TaskMgmtInstance.performAssignmentDelegation(TaskMgmtInstance.java:226)
	org.jbpm.taskmgmt.exe.TaskMgmtInstance.performAssignment(TaskMgmtInstance.java:199)

	org.jbpm.graph.node.TaskNode.execute(TaskNode.java:168)
	org.jbpm.graph.def.Node.enter(Node.java:318)


I don't understand what i'm doing wrong.

Regards,

O.M.
