Hi,
I want to use a common transaction manager for hibernate and activiti, but i can not! And i have read all internet resources for that! Hear is a simple scenario (which does not even use hibernate!!):
- Save variables in task
- Save variable in task#execution
- Complete task
@Component
public class TaskManager {
@Autowired TaskService taskService;
@Autowired RuntimeService runtimeService;
@Transactional
public void completeTask(CompleteTaskRequest request) {
Task task = taskService.createTaskQuery().taskId(request.getTaskId()).singleResult();
if (task == null) {
throw new ActivitiObjectNotFoundException("No task found");
}
taskService.setVariableLocal(task.getId(), "actionDisplayUrl", request.getActionDisplayUrl());
taskService.setVariableLocal(task.getId(), "actionSummaryUrl", request.getActionSummaryUrl());
runtimeService.setVariableLocal(task.getExecutionId(), "prevTaskId", task.getId());
taskService.complete(task.getId());
}
}
It's obvious: if taskService.complete throws error, the whole transaction should be rollbacked. so the below test case should be passed:
@Deployment(resources = "org.activiti.test/CompleteTaskTest.bpmn20.xml")
public void testCompleteTaskWithError() {
Map<String, Object> processVars = new HashMap<>();
processVars.put("error", true); // Causes throwing error in ScriptTaskListener
runtimeService.startProcessInstanceByKey("CompleteTaskTest", processVars);
Task task = taskService.createTaskQuery().taskName("Task 1").singleResult();
CompleteTaskRequest req = new CompleteTaskRequest();
req.setTaskId(task.getId());
req.setActionDisplayUrl("/actions/1234");
req.setActionSummaryUrl("/actions/1234/summary");
try {
taskManager.completeTask(req);
fail("An error expected!");
} catch(Exception e) {
}
// Check variables rollback
assertNull(taskService.getVariableLocal(task.getId(),"actionSummaryUrl"));
assertNull(taskService.getVariableLocal(task.getId(),"actionDisplayUrl"));
assertNull(runtimeService.getVariableLocal(task.getExecutionId(), "prevTaskId"));
}
But it fails, the variables are committed to DB (not rollbacked).

Versions:
- Activiti version: 5.22.0
- DB: h2 (Also tested with Oracle in production)
What is wrong with my configurations?
The project is attached (Test cases are in TaskManagerTest class).
