-------------------------------------

I have read the documentation. Where does it say this is not supported?

> If an entity is mapped with a set of components ("composite-elements"), bulk delete of the entity fails with a foreign key constraint violation because Hibernate does not delete the contents of the child table. For example, suppose we have two POJOs:
> public class Person {
>   private Long m_id;
>   private Set m_aliases = new HashSet();
>   .. getters and setters not shown ...	
> }
> public class Name {
>   private String m_lastName;
>   .. getter and setter not shown ...	
> }
> And the entity is mapped as follows:
> <class name="Person" table="tbl_person">
>   <id name='id' column='objid'>
>     <generator class='native'/>
>   </id>
>   <set name="aliases" table="tbl_name_aliases" lazy="false" cascade="all,delete-orphan">
>     <key column="person_id"/>
>     <composite-element class="Name" >
>       <property name="lastName" column="last_name"/>
>     </composite-element>
>   </set>
> </class>		
> The following code generates an integrity constraint violation:
> Session sess = getSessionFactory().getCurrentSession();
> Person person = new Person();
> Name name = new Name();
> name.setLastName("Smith");
> person.getAliases().add(name);
> sess.saveOrUpdate(person);
> sess.flush();
> sess.createQuery("delete from Person").executeUpdate();  // FAILS!
