org.hibernate.collection.PersistentIndexedElementHolder.readFrom class cast problem
-----------------------------------------------------------------------------------

                 Key: HHH-3259
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3259
             Project: Hibernate3
          Issue Type: Bug
          Components: core
    Affects Versions: 3.2.6
            Reporter: Pascal P. Pochet


in 	"public Object readFrom(ResultSet rs, CollectionPersister persister, CollectionAliases descriptor, Object owner)"
the cast to NullableType at following line
>>>>		final String index = ( (NullableType) indexType ).toXMLString( indexValue, factory );
causes a class cast exception if the entity contains an attribute defined by an user type when converting to textual representation 
the dom4j.Element obtained from a EntityMode.DOM4J session.

In that situation the indexType is a CustomType which doesn't inherit from NullableType.

Solution could be to make "toXMLString" (and other xml-serialization related functions) member of an interface that the subclasses of AbstractType should implement
or to move them to AbstractType itself and then change the cast accordingly to chosen solution.
