[hibernate-issues] [Hibernate-JIRA] Commented: (ANN-558) @OneToMany(mappedBy="") can not recognize properties in parent classes

]
David Hay commented on ANN-558:
-------------------------------
Why is this a bad idea? Is seems like it goes against the normal inheritance model of
Java. If the mappedBy property can't be found in the child class, but it's found
in the parent class it should use that, especially if the inheritance strategy is single
table. Could you point me at some documentation that explains why such a mapping is a bad
idea? Thanks!
@OneToMany(mappedBy="") can not recognize properties in
parent classes
----------------------------------------------------------------------
Key: ANN-558
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-558
Project: Hibernate Annotations
Issue Type: Bug
Components: binder
Affects Versions: 3.2.1
Reporter: Amir Pashazadeh
@Entity
@Inheritance(strategy=InheritanceType.SINGLE_TABLE)
public class A {
@ManyToOne
private B b;
}
@Entity
@DiscriminatorValue("c")
public class C extends A {
}
@Entity
public class B {
@OneToMany(mappedBy="b")
private List<C> cs;
}
there would be an exception in this mapping, and it says that there is no such property
found in C class (which is mapped by "b")
------
by the way I'm not sure whether this is a Hibernate Annotations bug, or a Hibernate
Core bug (I've not tested it without annotations).
