task-assign-events are sometimes fired when group assignment is performed ------------------------------------------------------------------------- Key: JBPM-1032 URL: http://jira.jboss.com/jira/browse/JBPM-1032 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2.1 Reporter: Karsten Dello Assigned To: Tom Baeyens A "task-assingn"-event is sometimes fired, if only group assignment (setting pooledActors) is performed. This always happens when a swimlane is in use which specifies pooled-actors (junit test 1). On the other hand, when the pooled-actors are expressed via an assignment-element as an child element of a task (junit test 2), the event is not fired. From my point of view the engine should either: a) not fire an task-assign-event in case of group assignments at all b) fire it consequently at all group assignments events c) fire a different event Ronald suggested in the forum thread (link above) to introduce a seperate event "task-group-assign" in case a task gets assigned to a group. In my opinion this would be the best solution to this problem. public void testTaskAssignIsFiredWithSwimlaneGroupAssignment() { ProcessDefinition processDefinition = ProcessDefinition.parseXmlString( "<process-definition name=\"someprocessxyz\">" + " <event type=\"task-assign\">" + " <script>System.out.println(\"task-assign-event fired!\");" + " executionContext.setVariable(\"task-assign-event-has-fired\",Boolean.TRUE);</script>"+ " </event>"+ " <start-state>" + " <transition to='a' />" + " </start-state>" + " <swimlane name='swimlane22'>"+ " <assignment pooled-actors='jan,nina'/>"+ " </swimlane>"+ " <task-node name='a'>" + " <task name='sometask' swimlane='swimlane22'/>" + " <transition to='end'/>"+ " </task-node>"+ " <end-state name='end' />" + "</process-definition>" ); ProcessInstance processInstance = new ProcessInstance(processDefinition); Token token = processInstance.getRootToken(); processInstance.signal(); Object o=processInstance.getContextInstance().getVariable("task-assign-event-has-fired"); assertEquals(Boolean.TRUE, o); } public void testTaskAssignIsNOTFiredWithSwimlaneGroupAssignment() { ProcessDefinition processDefinition = ProcessDefinition.parseXmlString( "<process-definition name=\"someprocessxyz\">" + " <event type=\"task-assign\">" + " <script>System.out.println(\"task-assign-event fired!\")"+ " executionContext.setVariable(\"task-assign-event-has-fired\",Boolean.TRUE);</script>"+ " </event>"+ " <start-state>" + " <transition to='a' />" + " </start-state>" + " <task-node name='a'>" + " <task name='sometask'>" + " <assignment pooled-actors='jan,nina'/>"+ " </task>"+ " <transition to='end'/>"+ " </task-node>"+ " <end-state name='end' />" + "</process-definition>" ); ProcessInstance processInstance = new ProcessInstance(processDefinition); Token token = processInstance.getRootToken(); processInstance.signal(); Object o=processInstance.getContextInstance().getVariable("task-assign-event-has-fired"); assertEquals(Boolean.TRUE, o); }
