[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3108) <load-collection role="entity_name.property"> doesn't work

[Marcin Mościcki (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3108?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_29801 ] 

Marcin Mościcki commented on HHH-3108:
--------------------------------------

Ok, I think I fixed it:
In org.hibernate.cfg.ResultSetMappingBinder, the entity name of the parent side of the relationship was automatically
prefixed with default package:

    String ownerClassName = HbmBinder.getClassName(collectionAttribute.substring( 0, dot ), mappings );

I changed this to:
		String ownerClassName = collectionAttribute.substring( 0, dot );
		if (mappings.getClass(ownerClassName)==null) {
			ownerClassName = HbmBinder.getClassName( ownerClassName, mappings );
		}

Below there's a comment:
		//FIXME: get the PersistentClass
		java.util.Map propertyResults = bindPropertyResults(alias, returnElem, null, mappings );

which might have alluded to this, or some other issue, I don't know.
Changed file attached - I used official 3.2.6.ga version available in bundled distribution - if you'd like a patch, please let me know to which tag.

> I use an <sql-query> for a <loader> in a collection owned by a named entity. The role attribute is set to "<entity-name>.<property-name>" - exactly the key under witch the collection's meta data is registered in SessionFactoryImpl.collectionPersisters map - but when the query is being added, SessionFactoryImpl looks for it under the key "<package>.<entity-name>.<property-name>" in this map, and doesn't find it.
> When entity-name attribute is removed from the entity mapping and unqualified class name is used to refer to it instead, everything works fine.
> The easiest, and probably most uniform solution would be to introduce a second attribute "entity-role" to the load-collection element.
> The following exception results from mapping:
> <hibernate-mapping package="hibernatedemo.model">
> ....
> <class table="persons_test" entity-name="person" name="Person">
> ....

> 			<key/>
> 			<one-to-many entity-name="person_map"/>
> 			<loader query-ref="fetch_person_map_by_person"/>
> 		</set>
> </class>
> 	<sql-query name="fetch_person_map_by_person">
