<load-collection role="entity_name.property"> doesn't work
----------------------------------------------------------
Key: HHH-3108
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3108
Project: Hibernate3
Issue Type: Bug
Components: metamodel
Affects Versions: 3.2.6
Environment: Hibernate 3.2.6, Oracle 9 (insignificant)
Reporter: Marcin Mościcki
Priority: Minor
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">

I meant here that there is no exception thrown - the collection returned is incorrectly
empty, but I believe there already is a bug report on that.

Marcin Mościcki updated HHH-3108:
---------------------------------
Attachment: hibernatebug.zip
I attach a simple test case to show the problem.
Contains two classes - Parent and Child, tested using three mappings:
1) custom sql-query as a set loader using entity names: unresolved collection exception
2) custom sql-query as a set loader using class names: returns empty collections
3) standard mapping without a specific loader as a reference: works ok.
db.sql contains schema with two tables and example data. Run on an Oracle database.
Maybe 2) is the same as HHH-420, or maybe it's not even a bug, but it looks just as in
hibernate reference...

--------------------------------------
Ok,
the problem with issue 2) (empty collection) was caused by missing 'column'
attribute for <key> element inside the <set>.
This is, however, how it was presented in the hibernate docs...
Issue 1) remains - I'll have a deeper look at it later.

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.
