I'm wondering if CascadeType.DELETE_ORPHAN is supposed to work with one-to-one relationships. Below is some example code of what I'm trying to do.

Hibernate version: 3.1.1

Mapping documents: 3.1-beta8

Code:

Code:

@Entity
public class Dog extends DomainObject {
   ...
   @OneToOne( mappedBy = "dog", cascade = CascadeType.ALL )
   @Cascade( org.hibernate.annotations.CascadeType.DELETE_ORPHAN )
   private CachedArticle cachedArticle;
   ...
}

@Entity
public class Collar extends DomainObject {
   ...
   @OneToOne
   private Dog dog;
   ...
}

Dog dog = dogDao.getDog( 1 );
Collar collar = dog.getCollar();
assertTrue( collar != null );

dog.setCollar( null );
dog = dogDao.saveDog( dog );
collar = collarDao.getCollar( collar.getId() );
assertTrue( collar == null );
