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: Hibernate Core 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) at org.hibernate.cfg.Configuration.parseSessionFactory(Configuration.java:1568) at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1534) at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1508) at org.hibernate.cfg.Configuration.configure(Configuration.java:1428)
