Hello!

I have a Customer object which contains a unidirectional collection (Set) of ContactPersons (embedded entities).

Cascading for this relation is set to "all,delete-orphans". It works correctly but what I'm wondering about is why Hibernate entirely deletes and re-inserts the ContactPersons every time I update the Customer.

The object graph is in detached state as I get it from a remote client.

I have implemented equals() and hashCode() according to the recommendations of the Hibernate documentation.

I'd appreciate any help.

Best regards,

Fabian

I forgot to mention that I'm using the convenience update() method of Spring's HibernateTemplate.
