[hibernate-issues] [Hibernate-JIRA] Created: (HHH-6905) Getting invalid ID on cascade (using @DiscriminatorColumn)

Getting invalid ID on cascade (using @DiscriminatorColumn) ---------------------------------------------------------- Key: HHH-6905 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6905 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 4.0.0.CR4 Environment: JPA 2 / Hibernate 4.0.0.CR4, Postgres 9, Linux (Ubuntu 11.10) Reporter: Rogério Lino Priority: Minor When try to persist a entity with a list (@OneToMany), the id returned to save in cascade is the value of discriminator column (int). Ex: @Entity @Table(name = "person") @Inheritance(strategy = InheritanceType.SINGLE_TABLE) @DiscriminatorColumn(name = "type", discriminatorType = DiscriminatorType.INTEGER) class Person extends MappedSuperClassWithId { } ---- @Entity @DiscriminatorValue("9999") class Employee extends Person { @OneToMany(cascade = CascadeType.ALL, mappedBy = "employee") private List<Phone> phones; } ---- Employee employee = new Employee(); // employee setters Phone phone = new Phone(); // employee setters employee.getPhones().add(phone); entityManager.persist(employee); // throw org.hibernate.exception.ConstraintViolationException // ERROR: insert or update on table "phone" violates foreign key constraint "..." // Detail: Key (id_employee)=(9999) is not present in table "person". ---- The column order in the table person (generated by hibernate.hbm2ddl.auto) is "type" and "id". When I change to "id" and "type", works fine. For some reason Hibernate is getting as last id the value of first table column. -- This message is automatically generated by JIRA.
