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)

| Exception in thread "main"
What is wrong? What I have to do?
Thank you,
nort
