Terminating an active process instance

amuthuse — Thu, 14 Jun 2012 10:40:59 GMT

How do we terminate a process instance. I see APIs for suspending and resuming a process. But nothing as such for terminating a process.We do have such business use cases.For example, in a loan approval process, while the process is underway, the applicant might come up with a cancellation request.

Pls don't treat this as an authoritative answer. Just sharing my point of view:

1. The BPMN on level of its definition manages all cases including cancellation. It can be done by boundary event or so. Check the UM for details

2. Completely delete the process instance with RuntimeServicedeleteProcessInstance(String processInstanceId, String deleteReason). Then you loose the history I bet.

Hi;
cancel activity of boundary event is not working properly. (I am waiting for this property.) Is there any development on this subject.
When I check the status of item; I see it is resolved. İs there anyone who will validate it is solved.

I tried it on activiti 5.9.3. It does not work when cancel activity is set false.

I couldnt find enough info about the first approach in UM. I would appriciate if you/anyone share some more details about it.

second approach, wont be applicable to most of the usecases, since we cant afford to lose the history.

I encountered the same problem, then I found out that when you delete a process instance, activiti engine just remove the process instance from active process instances, and make a 'delete reason' mark on the historic process instance, all the historic record will be kept in database.
so if you want to terminate a process instance, you just call runtimService.deleteProcessInstance()
