We are using Hibernate envers to store historical revisions of the data, there is a requirement to revert data to a certain revision. As we are using the Version column to use the optimistic locking approach, when I try to save data from the previous revision I get a StaleObjectException. Is there any way to force Hibernate to store data from previous revision?

Very good question. Can you show us how you're doing it? Trying to load the revision and then saving it? copying from the revision to the actual object? – Lucas de Oliveira Apr 06 '11 at 09:54

I am trying to load the revision and saving it using the merge method of javax.persistence.EntityManager. – Rakesh Apr 06 '11 at 10:45

That's an awesome question. I didn't find anything like that in the envers documentation but I'm sure it's a common issue. As a workaround you could set the attributes on the desired object revision (in a constructor for instance)

2It is a painful workaround, but look like there is no other alternative. – Rakesh Apr 07 '11 at 17:41
