Multi Instance User task with timer boundary event

[sai576]

Hi,

    Is it possible Multi Instance User task with timer boundary event.Actually i created multi instance user task with list of users is assigned in collection variable,now my doubt is suppose i attach timer boundary event to this multi instance user task.After timer expires is shifted to next user in user list.Suppose there is list of users USER1,USER2,USER3 if user1 not complete the task with in the time i want to shift next user USER2.I tried this one but i get timer entity was updated by another transaction?Can anyone explain how to solve this scenario?

The 'updated by another transaction' means that two threads are at the same time trying to update the same data. In theory, what you describe would work. Do you have a unit test?
