Hi!

I have found a few answers to this, but I kindof did not get it:

I need to make a copy of an entity, change a few values and then save that object with a new id (resulting in an insert rather than an update). Maybe my problem is that the id is a long (and generated in the database)

I cant implement a .clone method.

If I "evict" the original object, and save it, it will result in an error because the id (obviously) is already in use. If I change the id (which is a long) manually to "0" or "-1" (which I thought would be hibernate for "new") hibernate will just save it with the id "0" and the next iteration obviously that will through an error.

So, how can do that, dont get it!??

Thanks a loads!

Cheers!

I would simply get the object, create a new object, get the data from the first and set the data in the new.
Don't touch the id, so it will stay to the default. I think then it should make a new id when inserting in the DB.

Hey mate, thanks for your answer!

Do you think there is a way without having to copy the data from one object to the other? Those objects have about 20 fields each, and there are about a dozen. Thats a lot of not so nice code!

Thanks!

Don't know if Hibernate can help you, but you could make a simple method to do it.
