Jesse Sweetland commented on ANN-698:
-------------------------------------
I've run into the same issue and I think the problem has more to do with the fact that
the initial mapping validation logic looks at both fields and properties before deciding
whether field annotations or property annotations are being used. In my case I have
this:
@Entity
public class Foo<B extends Bar> implements Serializable {
private static final long serialVersionUID = 1L;
// ...
@ManyToOne
private Bar bar;
// ...
public B getBar() {
return (B)bar;
}
public void setBar(B bar) {
this.bar = bar;
}
}
In this case I'm using field annotations and mapping to a concrete entity type (Bar)
but using a properties to enforce strong typing. I can make Hibernate happy by putting
@Transient annotations on the accessor and mutator methods. Netbeans throws a fit, but it
compiles and deploys just fine.
Unbound property when default field access is used lead to unbound
AnnotationException

Key: ANN-698
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-698
Project: Hibernate Annotations
Issue Type: Bug
Affects Versions: 3.3.0.ga
Environment: hibernate3.jar: 3.2.5.ga
hibernate-annotations.jar: 3.3.0.GA
hibernate-commons-annotations.jar: 3.0.0.GA
hibernate-validator.jar: 3.0.0.GA
MySQL
Reporter: Sebastian Baltes
Fix For: 3.3.1.CR1
Attachments: log.txt
Transient fields are not ignored in Hibernate. I got an "Property has an unbound
type" exception and found no workaround.
Entity:
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Transient;
@Entity
public class Dummy<K> {
@Id
private Long id;
@Transient
transient private K dummyField;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public K getDummyField() {
return dummyField;
}
public void setDummyField(K dummyField) {
this.dummyField = dummyField;
}
}
Test Code:
EntityManager em = EntityManagerSingleton.get();
EntityTransaction tx = em.getTransaction();
tx.begin();
Dummy a = new Dummy();
em.persist(a);
tx.commit();
