[jboss-user] [JBoss jBPM] - Swimlane assigment

[nort]

Hello,

I want to run my first jbpm application and have some troubles with assigment of swimlanes. My configuration is that:

<process-definition
  |   xmlns="urn:jbpm.org:jpdl-3.1"  name="Urlaubsantrag">
  |    <swimlane name="Antragssteller">
  |       <assignment expression="group(applicant)"></assignment>
  |    </swimlane>
  |    <swimlane name="Vorgesetzer">
  |       <assignment expression="group(supervisor)"></assignment>
  |    </swimlane>
  |    <start-state name="Urlaubsantrag erstellen">
  |       <task name="Sende Urlaubsantrag" swimlane="Antragssteller">
  |          <controller>...
  |          </controller>
  |       </task>
  |       <transition name="Urlaubsantrag versenden" to="Urlaubsantrag entscheiden"></transition>
  |    </start-state>
  |    <end-state name="Ende"></end-state>
  |    <task-node name="Urlaubsantrag entscheiden">
  |       <task name="Urlaubsantrag lesen" swimlane="Vorgesetzer">
  |          <controller>...
  |          </controller>
  |       </task>
  |       <transition name="Urlaubsantrag bearbeitet" to="Ende"></transition>
  |    </task-node>
  | </process-definition>

I run the first task:

  | 		Token token = processInstance.getRootToken();
  | 		Node node = (Node)token.getNode();
  | 		System.out.println("Current node: "+node.getName());
  | 		
  | 		Task task = processInstance.getProcessDefinition().
  | 						getTaskMgmtDefinition().getStartTask();
  | 		
  | 		TaskInstance taskInstance = new TaskInstance(task.getName(), "Antragssteller");
  | 		token.signal("Urlaubsantrag versenden");
  | 
and get the exception:

Caused by: org.jbpm.identity.assignment.ExpressionAssignmentException: couldn't resolve assignment expression 'group(supervisor)'
  | 	at org.jbpm.identity.assignment.ExpressionAssignmentHandler.assign(ExpressionAssignmentHandler.java:97)
  | 	at org.jbpm.taskmgmt.exe.TaskMgmtInstance.performAssignmentDelegation(TaskMgmtInstance.java:217)

  | 	at org.jbpm.identity.assignment.ExpressionAssignmentHandler.assign(ExpressionAssignmentHandler.java:69)
  | 	... 13 more
  | Exception in thread "main" 

What is wrong? What I have to do?

Thank you,
nort
