Saveorupdate not updating
Problem is that your model has only one field and it’s primary key.When you’re trying to update your entity you change key’s value in the form and thus hibernate doesn’t know which entity it should update and creates a new entity instead.I am not using a update clause, but assuming that save ORUpdate should work. OR Should I catch constraint Violation Exception and do a forced "update" clause instead ?flush() method just synchronization with the db and then you need to commit or clear the session to see the changes. It automatically flushes and you can see your changes from another session too.
If the object is already in the session with the same identifier, then it throws exception.
If you use string foreign key it would be difficult to update other tables, especially if they have lots of records.
