HI,

I have a named query  like this:

 <sql-query name="loadMDGraphJoined-AllPathFromAndToChildSlow">
        <return-join alias="parent" property="goe.parent"/>
        <return-join alias="child" property="goe.child"/>        
        <return alias="goe" class="com.ecg.mts.tsm.impl.domain.MasterDataEdge"/>        
        <![CDATA[
            select 
               pa.id AS {parent.id},
               pa.periodstart AS {parent.validPeriod.start},
               pa.periodend AS {parent.validPeriod.end},
               pa.shortdesc AS {parent.shortDesc},
               pa.longdesc AS {parent.longDesc},
               pa.name AS {parent.name},
               pa.class AS {parent.class},
               pa.clientid AS {parent.clientId},
               ch.id AS {child.id},
               ch.periodstart AS {child.validPeriod.start},
               ch.periodend AS {child.validPeriod.end},
               ch.shortdesc AS {child.shortDesc},
               ch.longdesc AS {child.longDesc},
               ch.name AS {child.name},
               ch.class AS {child.class},
               ch.clientid AS {child.clientId},               
               goe.parent_id AS {goe.parent},
               goe.child_id AS {goe.child},
               goe.id AS {goe.id}
            from tsm_master_data pa, tsm_master_data ch,
                (select DISTINCT ROWID, goe.* from tsm_master_data_edge goe  
                 start with  parent_id in (   
                                             ( /* Selection der Pfade nach "oben" */
                                                SELECT DISTINCT goe2.parent_id
                                                FROM   tsm_master_data_edge goe2
                                                START WITH goe2.child_id = :parentId
                                                OR goe2.child_id IN ((SELECT DISTINCT child_id
								 				  	   FROM tsm_master_data_edge 
													   START WITH parent_id = :parentId
													   CONNECT BY PRIOR parent_id = child_id))
                                                CONNECT BY PRIOR goe2.parent_id = goe2.child_id
                                             )
                                          ) or parent_id = :parentId
                 connect by prior goe.child_id = goe.parent_id) goe
            where pa.id = goe.parent_id
            and ch.id = goe.child_id                 
            ]]>
</sql-query>

And I call it like this (using spring):

List items = getHibernateTemplate().findByNamedQueryAndNamedParam(
                "loadMDGraphJoined-AllPathFromAndToChildSlow", "parentId", id);

This works fine with Core 3.2.0rc2 and annotations 3.2.0rc1. After switching to 3.2.0GA  I got the following exception:

org.springframework.orm.hibernate3.HibernateSystemException: Could not determine fetch owner : null; nested exception is org.hibernate.HibernateException: Could not determine fetch owner : null

The variable "entityName" in CustomerLoader.determineAppropriateOwnerPersister() ist null because the parameter ownerDescriptor ist null. This is because EntityFetchReturn.getOwner also returns null at line 146.
