[hibernate-issues] [Hibernate-JIRA] Created: (ANN-686) SubClass with EmbeddedId or IdClass containing @ManyToOne fail at startup
SubClass with EmbeddedId or IdClass containing @ManyToOne fail at startup
-------------------------------------------------------------------------
Key: ANN-686
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-686
Project: Hibernate Annotations
Issue Type: Bug
Affects Versions: 3.3.1.beta1, 3.3.0.ga
Reporter: Marcos Sousa
Priority: Minor
I subclass Customer that has a EmbeddedId using JOIN inheritance strategy. My embeddable
class has @ManyToOne relationship. Look the classes:
Pesson class:
@Entity
@Table(name="person")
public class Person {
@Id
private Integer personId;
private String name;
}
Embeddable class ID.
@Embeddable
public class PersonPk implements Serializable {
@ManyToOne(optional=false,
cascade={CascadeType.PERSIST,
CascadeType.REFRESH,
CascadeType.REMOVE}, fetch=FetchType.EAGER)
@JoinColumn(name="personId")
private Person person;
// ... getters and setters
}
CustomerClass:
@Entity
@Table(name="Customer")
@Inheritance(strategy=InheritanceType.JOINED)
public class Customer {
@Id
private PersonPk pk = new PersonPk();
}
Regional Custumer:
@Entity
@Table(name="AmericanCustomer")
@PrimaryKeyJoinColumn(name="personId")
@IdClass(PessoaPk.class)
public class AmericanCustomer extends Customer {
// some american customer fields..
}
This mapping throw this exception at hibernate startup:
Invocation of init method failed; nested exception is java.util.NoSuchElementException
