setting assignee on DelegateTask is not stored in HistoricTaskInstance

[flaviodonze]

After using a org.activiti.engine.delegate.TaskListener to set the assignee of a DelegateTask, the HistoricTaskInstance.assignee is not set.

public class TestListener implements TaskListener {
	@Override
	public void notify(DelegateTask delegateTask) {
		delegateTask.setAssignee("Person_system");
	}
}

<process id="TestFlow" isExecutable="true">
	<startEvent id="start" activiti:initiator="initiator"/>
	<sequenceFlow id="startToForward" sourceRef="start" targetRef="testListener"/>

	<userTask id="testListener" name="testListener">
		<extensionElements>
			<activiti:taskListener event="create" class="TestListener" />
		</extensionElements>
	</userTask>
        .....

Using the taskservice works, taskService.createTaskQuery().list() I get the task with correct assignee set:

Using the historyservice results in outdated tasks: historyService.createHistoricTaskInstanceQuery().list()

Results in an empty array: historyService.createHistoricTaskInstanceQuery().taskAssignee("Person_system").list();

Using Activiti Version 7.3.0

UPDATE: Just verified the same issue in Activiti Version 6.0.0

Here a print-screen which shows the error in the database, comparing the two task tables of the running and history:

Here is a workaround I came up with, this fixes the issue in the database, ACT_HI_TASKINST contains the assignee.

// TODO: Hack to make sure history-task is updated with active-task (e.g. assignee), required after update V5 > V6
// https://github.com/Activiti/Activiti/issues/3973
runtimeService.addEventListener(new ActivitiEventListener() {
	@Override
	public void onEvent(ActivitiEvent event) {
		ActivitiEntityEvent entityEvent = (ActivitiEntityEvent) event;
		TaskEntity task = (TaskEntity) entityEvent.getEntity();
		processEngine.getManagementService().executeCommand(new SaveTaskCmd(task));
	}

	@Override
	public boolean isFailOnException() {
		return false;
	}
}, ActivitiEventType.TASK_CREATED);
