criteria failing with custom user type -------------------------------------- Key: HHH-2491 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2491 Project: Hibernate3 Type: Bug Environment: hibernate 3.2.2-GA hsqldb 8.0.1 Reporter: Luca Dall'Olio When executing a criteria query with a custom <id> type, hibernate ignores the custom type trying to set a primitive type instead; whereas load() works succesfully : Below is some code that helps reproducing this problem : Example of a custom Identifier Generator : package sample; ... public class CustomIdentifierGenerator implements IdentifierGenerator, PostInsertIdentifierGenerator, Configurable { private static IdentityGenerator hibernateGeneratorDelegate = null; public void configure(Type type, Properties props, Dialect dialect) throws MappingException { hibernateGeneratorDelegate = IdentifierGeneratorFactory.create( "sequence", new LongType(), props, dialect); if (hibernateGeneratorDelegate instanceof Configurable) { ((Configurable) hibernateGeneratorDelegate).configure( new LongType(), props, dialect); } } public Serializable generate(SessionImplementor session, Object object) throws HibernateException { return hibernateGeneratorDelegate.generate(session, object); } public InsertGeneratedIdentifierDelegate getInsertGeneratedIdentifierDelegate( PostInsertIdentityPersister persister, Dialect dialect, boolean isUseGet) throws HibernateException { return hibernateGeneratorDelegate.getInsertGeneratedIdentifierDelegate(persister, dialect, isUseGet); } } Mapping snippet : <class name="sample.SimpleEntity" table="TB_SMP_SIMPLE"> <id name="entityPK" type="sample.LongEntityPK" column="SMP_ID"> <generator class="sample.CustomIdentifierGenerator" /> </id> </class> Entity class : package sample; .... public class SimpleEntity { Query code : SimpleEntity de = new SimpleEntity(); s.save(de); // Read SimpleEntity de2 = (SimpleEntity) s.load(SimpleEntity.class, de .getEntityPK()); assertNotNull(de2); assertEquals(de, de2); // Query Criteria crit = s.createCriteria(SimpleEntity.class); List results = crit.list(); // FAILING!!!
