Hi,
I've encountered a problem when evaluating the task activity of jBPM4. Unfortunately
the forum search is down at the moment, but I haven't found any posts regarding that
issue when searching manually ;)
Configuration:
- jBPM4.0 standalone out of the box, only changed DB to MySQL5
- JDK/Container: Java(TM) SE Runtime Environment (build 1.6.0_14-b08)
Process definition:
| <?xml version="1.0" encoding="UTF-8"?>
|
| <process name="tasktest" xmlns="http://jbpm.org/4.0/jpdl">
| <start name="start" g="77,110,48,48">
| <transition name="to task" to="task" g="-36,-20"
/>
| </start>
| <task assignee="freiburger" name="task"
g="206,127,92,52">
| <transition name="to wait" to="wait" g="-36,-20"
/>
| </task>
| <state name="wait" g="401,154,92,52">
| <transition name="to end" to="end" g="-41,-20"
/>
| </state>
| <end name="end" g="543,121,48,48" />
| </process>
|
API using JbpmTestCase:
| public void testTakeTask() {
| /* Create process instance */
| ProcessInstance processInstance = executionService
| .startProcessInstanceByKey("tasktest");
|
| /* Find tasks for freiburger (1 expected) */
| List<Task> taskList = taskService.findPersonalTasks("freiburger");
| assertEquals(1, taskList.size());
| Task task = taskList.get(0);
| assertEquals("task", task.getName());
| assertEquals("freiburger", task.getAssignee());
|
| /* Complete task */
| taskService.completeTask(task.getId());
|
| /* Find tasks for freiburger (0 expected) */
| taskList = taskService.findPersonalTasks("freiburger");
| assertEquals(0, taskList.size());
|
| /* Find active activities ("wait" expected) */
| Set<String> expectedActivityNames = new HashSet<String>();
| expectedActivityNames.add("wait");
| assertEquals(expectedActivityNames, processInstance
| .findActiveActivityNames());
| }
|

Problem description
So obviously the task was not removed from the current activities after completion. Still
the engine moves on to the next activity, but it doesn't show up in the activity list
at all. I quite don't understand this behaviour if it is intended, any help is greatly
appreciated.
Thanks!
