Hello every body. I have an objects witch has a lot of sets (customers, suppliers...), when the application loads, all the sets are loaded from the database. If I try for example to insert a new customer in the database, if there is no previous values in the DB every thing works fine and the record is created but if the table customer alreday contains records I got the exception: com.app.hibernate.PersistenceException: a different object with the same identifier value was already associated with the session: 257, of class: com.app.model.fields.OEM.
Each company has a collection of customers and each customer has a collection of oems.
Hibernate version:2.1.7
