-------------------------------------------------------------------------
Key: HHH-2172
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2172
Project: Hibernate3
Type: Bug
Versions: 3.2.0.ga
Environment: Annotations 3.2.0GA (16.10.06)
Core 3.2.0GA (16.10.06)
Reporter: Alexander Rupsch
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.
