[Radosław Smogura (JIRA)]

Composite PK and @GeneratedValue
--------------------------------

                 Key: EJB-364
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-364
             Project: Hibernate Entity Manager
          Issue Type: Bug
    Affects Versions: 3.3.2.GA
         Environment: Hibernate 3.2.6
Glassfish
PostgreSQL
            Reporter: Radosław Smogura
            Priority: Critical


[code]
For class like this
@Entity
@IdClass(FooId.class)
/* Seq / Table generator */
public class Foo {
  int id1;
 int id2;

@Id
public getId1() {
return id1;
}
public setId1(....);

@Id
@GeneratedValue(strategy=AUTO/IDENTITY/SEQUENCE/TABLE)
public int getId2() {
return id2;
}

public void setId2(.....);
}
[/code]
Id1 is set manully, but id2 is unchanged i this situation hibernate doesn't generates PK and tries to insert NULL  causing error.

Specification requires assigning of generated value with @Id properties. Part 2.4.1 defines two types of PKs simple and composite and part 9.1.9 says about PKs in generally.  (SEQ or IDENTITY is specification depended, but PostgreSQL support it and Hibernate should support it too).
