[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2368) Bulk delete fails when entity has a collection of composite-elements

Bulk delete fails when entity has a collection of composite-elements -------------------------------------------------------------------- Key: HHH-2368 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2368 Project: Hibernate3 Type: Bug

Components: core Versions: 3.2.1 Environment: Hibernate 3.2.1, Oracle 10g Reporter: Rob Hasselbaum

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!
