type
--------------------------------------------------------------------------------------------
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

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();
