Hello I have a small problem.

I got a table in my database that contains an ID which is manually assigned (it is inserted through a form id input field that a user types).

Now I want to change this ID but Hibernate does not want to update the id attached to the object.

I assume this is because Hibernate does not know what the old ID was (or is there some property in the mapping files to enable this?), is there any way to edit an existing ID into a new one without removing the entire record and reinserting it with the new id ?

Thanks (my mapping is just a standard <id> without a generator)

No there is not. If you change a primary key, you are essentially inserting a new object into your database. Hibernate enforces that principle by not allowing you to change primary keys.

Best bet is to re-insert it with your new primary key and delete the old entry.
