[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5648) Auto-increment IDs should be assigned upon commit (or hooks made available)

Auto-increment IDs should be assigned upon commit (or hooks made available) --------------------------------------------------------------------------- Key: HHH-5648 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5648 Project: Hibernate Core Issue Type: Bug Components: core Environment: v3.6, mysql Reporter: Wallace Wadge The connection pool BoneCP (http://jolbox.com) has support to automatically replay a transaction when a database/network goes down. Under hibernate, since objects get their IDs populated upon INSERTs, the following sequence of events is possible: BEGIN TRANSACTION INSERT STATEMENT (object gets the ID field populated) => network goes down, new connection is given and transaction is replayed beneath hibernate COMMIT TRANSACTION Now the database has given us a new ID but hibernate never had a chance to update the object properly. To fix: either assign the IDs upon a successful transaction commit or at least provide some kind of hooking mechanism so as to correct the problematic objects.
