Hi all,

Activiti version: 5.8

Is there a way to assign an user task when the creation event is intercepted ?

What I want to do is when a task is created, I would like to assign it to an user.
I'm using the interface TaskListener to intercept the create event. In the notify method, I'm trying to set assignee but the task does not exist yet in database. Then there is a ProcessEngineException which has sens.

Here is the code:

public final class TacheSuspendueTaskListener implements TaskListener {

    @Autowired
    private UtilisateurRepositoryService utilisateurRepositoryService;

    @Autowired
    private MoteurProcessusService moteurProcessusService;
    
    @Autowired
    private TaskService activitiTaskService;

    @Override
    public void notify(DelegateTask delegateTask) {
        String lastAssignee = (String) delegateTask.getVariable("lastAssignee");
        if (lastAssignee != null) {
            List<Utilisateur> utilisateur = utilisateurRepositoryService.findByIdList(Lists.newArrayList(Long.valueOf(lastAssignee)));
        try {
            activitiTaskService.setAssignee(delegateTask.getId(), utilisateur.iterator().next().getId());
        } catch (ActivitiException ae) {
            throw new ProcessEngineException("Unable to assign task with taskId={} to user with userId={}.", ae,
                    delegateTask.getId(), utilisateur.iterator().next().getId());
        }

        }

    }
}

My 1st question is that am I wrong using the TaskListener to achieve what I want to do ?
2nd question, if I'm wrong is there another way to achieve this without using the TaskListener ?

Thanks for advices.

Use the delegateTask.setAssignee() instead of using the service, this will set the field on the entity that is about to be persisted…
