Bottom line (by [~yrodiere]): the problem only arises if you have a final method in one of your entities, or if you directly access fields from an external object and bytecode enhancement is not enabled. In both cases, Hibernate ORM proxies cannot work correctly (see HHH-11550).
We worked around the problem, making it less likely when doing full text queries by avoiding the retrieval of proxies as much as possible.

Hibernate Search 5.7.0.Beta2 when returning a single entry does not populate the field annotated with @id.
This is the test code, however I can't get it to run. I see this error in my application.
{code:java}
package org.hibernate.search.bugs;
import static org.junit.Assert.assertEquals;

public class YourTestCase extends SearchTestBase {
@Override

return new Class<?>[]{ YourAnnotatedEntity.class };
}
@Test

public void testSingletonNonIdSetBug() {
Session s = openSession();
YourAnnotatedEntity yourEntity1 = new YourAnnotatedEntity( 0L, "example" );
YourAnnotatedEntity yourEntity2 = new YourAnnotatedEntity( 1L, "alpha" );
Transaction tx = s.beginTransaction();
s.persist( yourEntity1 );
s.persist( yourEntity2 );
tx.commit();
FullTextSession session = Search.getFullTextSession( s );
QueryBuilder qb = session.getSearchFactory().buildQueryBuilder().forEntity( YourAnnotatedEntity.class ).get();
Query query = qb.keyword().onField( "name" ).matching( "example" ).createQuery();
List<YourAnnotatedEntity> result = (List<YourAnnotatedEntity>) session.createFullTextQuery( query ).list();
assertEquals( 1, result.size() );
assertEquals( 0L, (long) result.get( 0 ).getId() );
s.close();
}
}
{code}
Where I expect it to fail is in the line
{code:java}
assertEquals( 0L, (long) result.get( 0 ).getId() );
{code}
Because in my code, although _luke_ shows the {{@id}} values are there, they aren't populated in the returned entity, they are null.
On queries with multiple results, the {{@id}} values are populated.

I can't get this to work with these versions in the supplied pom.xml
{code:xml}

I get

Any help appreciated. |
