Try subscriber.close() before unsubscribe.

[JBoss jBPM] - dynamically create tasks
by AJanz
i got the following code to generate dynamically tasks on a node.
| public Object execute(JbpmContext jbpmContext) throws Exception {
| // TODO Auto-generated method stub
| // TODO Auto-generated method stub
|
| Boolean b;
| try {
| b = Boolean.TRUE;
| ProcessInstance pi = jbpmContext
| .loadProcessInstance(processid);
| for (int i = 0; i < actors.size(); i++) {
| String actor = (String) actors.get(i);
| TaskInstance ti = pi.getTaskMgmtInstance()
| .createTaskInstance();
| ti.setActorId(actor);
| jbpmContext.save(ti);
| }
| jbpmContext.save(pi);
| } catch (Exception e) {
| // TODO: handle exception
| e.printStackTrace();
| b= Boolean.FALSE;
| }
| return b;
| }
|
|
sometimes i got a nullpointer exception on
TaskInstance ti = pi.getTaskMgmtInstance()
the processid is set correct.
any idea what might be wrong?
