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 :
