[GSS](7.2.z) HHH-13084: Querying entity with non-ID property named 'id' fails if entity has an IdClass composite key

XMLWordPrintable

    • Hide 
      @Entity(name = "Person")
@IdClass(PersonId.class)
public static class Person implements Serializable {
    @Id
    private String name;

    @Id
    @Column( name = "ind")
    private int index;
    private Integer id;
}

      Executing the following query results in a NullPointerException:

      s.createQuery( "from Person p where p.id is null", Person.class ).list()

      Show
      @Entity(name = "Person" ) @IdClass(PersonId.class) public static class Person implements Serializable { @Id private String name; @Id @Column( name = "ind" ) private int index; private Integer id; } Executing the following query results in a NullPointerException: s.createQuery( "from Person p where p.id is null", Person.class ).list()

      Query failure with exception like:
