Lets assume the following mapping:
{code}
@Entity
@Audited
public class PersonDocument implements Serializable {
@Id
@ManyToOne(optional = false)
private Person person;
@Id
@ManyToOne(optional = false)
private Document document;
}
{code}
Unfortunately when using the above entity to locate revisions using the following query:
{code}
auditReader.createQuery().forRevisionsOfEntity( PersonDocument.class, false, true )
.add( AuditEntity.relatedId( "person" ).eq( 42 ) )
.addOrder( AuditEntity.revisionNumber().desc() );
{code}
Hibernate Envers will generate the following exception:
{noformat}
org.hibernate.envers.exception.AuditException: This criterion can only be used on a property that is a relation to another property.

{noformat}
The reason this fails is because the mapping configuration for the audited entity does not register relation mappings for properties annotated with {{@Id}}. |
