[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-6486) Negative ID created using Sequences

Negative ID created using Sequences ----------------------------------- Key: HHH-6486 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6486 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 4.0.0.Beta1, 4.0.0.Beta4 Environment: JBoss 7.0.0.Final with Hibernate 4.0.0.Beta4, Oracle 10 Express Reporter: Andreas Beckers We use seperated sequences for each table. Our IDs are annotated like this: @SequenceGenerator(name = "PersonGen", sequenceName = "person_id_seq") @Id @GeneratedValue(generator = "PersonGen") public long getId() { return _id; } The sequence is defined like this: CREATE SEQUENCE person_id_seq START WITH 1 INCREMENT BY 1 NOCACHE; The Problem is, that I get negative IDs in my object and the generated IDs are not unique. I get the error java.sql.SQLIntegrityConstraintViolationException: ORA-00001: Unique Constraint (VESUVZPONF.PERSON_PKEY) verletzt In the log I see: Generated identifier: -21, using strategy: org.hibernate.id.enhanced.SequenceStyleGenerator The code worked in JBoss 6.0.0.Final using Hibernate 3.6.0.Final I tried auto strategy which uses a single sequence that works fine. There are ManyToOne and OneToMany relations with cascade all, don't know if that's of importance.
