Hi there. Let's suppose there is a top level entiry object called ClaimCase. In each claim case you can have 0+ instances of Party. Party can be subclassed, examples are Claimant, Employer and EmployerClaimant.
Also, each ClaimCase can have 0+ instance of Requirement and each instance of Requirement can be 0+ instance of Activity.

I've noticed that when we save by using session.persist(), even if I changed only one thing in ClaimCase (topmost object) or in Activity (bottomost object), the entire object gets updated. (Meaning that the ClaimCase, Employer, Claimant, EmployerClaimant, Requirement and Activities for the claim case are updated ... because when I look at the database, I discovered all the version numbers are changed. Wondering if anyone else experience the same thing and is there a way to tell Hibernate to "smart" update?
