CLONE -Impossible to define caching for a subclass's collection in hibernate.cgf.xml
-------------------------------------------------------------------------------------
Key: HHH-2808
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2808
Project: Hibernate3
Issue Type: Bug
Components: caching (L2)
Affects Versions: 3.2.5
Environment: Hibernate 3.2.5
Sybase
Reporter: Sebastien Blind
Basically, hibernate allows to define <cache usage="transactional"/> inside the subclass mapping, i.e.
<subclass name="SubClass" extends="BaseClass" discriminator-value="xxx">
<bag name="subClassLinks" lazy="false" inverse="true" batch-size="100">
<cache usage="transactional" region="xxx"/>
<key column="xxx" not-null="true"/>
<one-to-many class="xxx"/>
</bag>
<join table="xxx">
</join>
</subclass>
but it's not allowed to do the same using <collection-cache collection="subClass.myCollection" region="xxx" usage="transactional"/>.
It throws:
Exception in thread "main" org.hibernate.MappingException: Cannot cache an unknown collection: subClass.myCollection
at org.hibernate.cfg.Configuration.setCollectionCacheConcurrencyStrategy(Configuration.java:1984)
