[hibernate-issues] [Hibernate-JIRA] Created: (HHH-2491) criteria failing with custom user type

[Luca Dall'Olio (JIRA)]

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!!! IllegalArgumentException in class: it.unimaticaspa.unique.pe.spec.entity.EntityBase, setter method of property: entityPK
                                                         //  expected type: it.unimaticaspa.unique.pe.spec.entity.IEntityPK, actual value: java.lang.Long


Logs :
