Jira issue originally created by user szjani:

When optimistick locking is being used, the version field is incremented after the update only if the entity itself has been modified. In Domain-Driven Design another kind of locking mechanism is essential: OPTIMISTICFORCEINCREMENT. It means that the version field is always incremented after an update. The lack of this feaure can be realized when only the aggregate root has a version field and some other parts of the aggregate is being modified.

PESSIMISTICFORCEINCREMENT is also an interesting lock type which might be useful as well.

I'm having this same issue, although I'm not certain a new locking-type is the answer.

Basically, I want to ensure that an entity gets updated with a new version integer/timestamp, whether or not anything "real" has been changed on it. It seems the only workaround is to designate a "junk" property and change that, which isn't particularly elegant.

The problem with a locking-type is that individual entities can't signal that they need incrementing without having a reference to the entity-manager so that they can $em->lock() .
