Cloning of a task

geekykrish

You need a TaskListener that listens for the completion event. Create a new task from the data you get in.

Now, the tricky thing is to set the process insance / execution id - how would you want to fit it in your process? It would need sequenflow and all that to work and to make the other logic work.

So i dont know if that's a good idea actually. What is your use case?

My use case in in certain scenario I will enter a parallel flow and at some point if a condition is true in the parallel flow i need to halt the parallel process and proceed the next user task in the flow once the user completes the task then i need to resume the parallel flow from the state in which it is halted.

I re-read your post multiple times, but i couldn't understand it, sorry. Can you please use punctuation in your sentences?

I have kind of same requirement, my use case is (In a particular scenario) when a process will move from 'taskA' to 'taskB'. The task should remain at both the places. I was thinking about either any clone functionality or may be a subTask, but I cannot see anything like that in the API. Can you please guide something?

jbarrez

No, that's not possible because it goes against the BPMN 2.0 spec.

What is your use case? I can't see anything directly that would need such functionality in a BPM system.

I have a use case like this: author submit an article to reviewer, the reviewer who was assigned to the task can further assign it to one or many reviewers at runtime to review. I thought that subtask can be created and assigned at runtime but I want subtask to see and do the same as parent task can do such as see attached article and author filled form. So the function is to create a subtask that is a clone of its parent task. Appreciate your help on how to implement this capability.

You could create a sub task and then in your UI logic gather all info attached to the parent task.

Best regards,

Thanks, Tijs. If UI is not Java based, does Activiti REST API provides the same functionality as Activiti Engine Java API?

Thanks,
Aiming

trademak

Yes, it should provide the same functionality. And if not please raise it with us and we can add the requested functionality to the REST API.

Best regards,
