JIRA has it marked as closed/rejected and as of 3.1.3 I still see the bug/feature/design flaw/reasonable compromise (depending on your POV). If this were a democracy I'd vote to have H3 null the IDs and leave the other pojo fields alone.

so is this meant to be fixed or not guys?

This thread has been dead for a year, but unfortunately I don't think anything has changed.

At the least, could someone clarify what Steve meant in http://opensource.atlassian.com/projects/hibernate/browse/HHH-1014 by "(hint:) rolling back the object identifier"? I don't see anything in the docs that tells me how to remove an identifier from an object once it's been assigned.

As a workaround, try to set

Code:

unsaved-value="undefined"

in the mapping of the auto generated id; this forces Hibernate to check (executing a SELECT) if the object is in the DB or not, regardless of the id value.
In this way you have an unnecessary SELECT, but Hibernate will insert your object instead of trying to update it.
Anyway I agree with you: since Hibernate automatically sets autogenerated ids, Hibernate should automatically reset ids to their unsaved-value during rollback of transaction.

Hi,

Is there a solution for this in the current version? We've tried a few things, but none of them seem to work. (Including hibernate.use_identifer_rollback, which is apparently meant to be used for something else, and setting unsaved-value to "undefined", which drastically reduces the performance of batch saves.)

Cheers,
Peter

please just removed explicit setting of this java object

<timestamp column="UPD_TS" name="updateTimestamp" unsaved-value="null"/>

it will work

Thanks

I'm facing the same problem. Is there a solution for this?

just like other..
