Issue

I would like to have fields: creationDate and updateDate in Entity,

I would like to this fields to be updated in db on persist operation. But I would like to field creationDate will not be updated on merge operation in db.

I am looking for JPA annotation like this: @TransientOnMerge or @IgnoreOnMerge But cant find anything.

Is it possible? Can You help?
