Frank Schwarz commented on HHH-5390:
------------------------------------
Have you been looking for this phrase?:
JSR-317, p. 42: "Such schema-level mapping annotations must be specified on the
owning side of the relationship."
"Such" in this context is only referring to
"JoinColumn"/"JoinTable". "OrderColumn" is definitely not
meant here.
Further one can read:
JSR 317, p.406: "The OrderColumn annotation is specified on the side of the
relationship that references the collection that is to be ordered."
No restriction is stated here regarding uni-/bidirectionality of the relationship.
In consequence, the OP is wrong in demanding that a warning should be issued. This mapping
has to be supported in the course of full JPA 2.0 support.
Index column on inverse List should throw a warning
---------------------------------------------------
Key: HHH-5390
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-5390
Project: Hibernate Core
Issue Type: Improvement
Components: annotations
Affects Versions: 3.5.3
Reporter: Chris Bredesen
The manual correctly warns against trying to map an indexed inverse collection on a List.
However, a configuration containing this invalid mapping builds successfully but causes
null values to be inserted for the index column.
Hibernate should be helpful and, if possible, throw a warning to the user (perhaps an
error?) that explains the invalid combination. Here is an example that would run but
produce invalid results:
{code}
@Entity
public class Parent {
@OneToMany(mappedBy="parent")
@OrderColumn(name="order")
private List<Child> children;
}
@Entity
public class Child {
@ManyToOne
private Parent parent;
}
{code}
The above is a typical one to many with the addition of @OrderColumn. Because Child owns
the relationship, the index column is lost/ignored. Hibernate should warn about this.
