Kundera Redis plugin returns empty list on query - kundera

Question

I am trying to resolve a problem where I cannot return a list with Kundera query for redis back end. I have problem returning a single entity and no problem persistening entities. However when I try to do a simple select to return a single type it always returns me an empty list.

Here is the entity that I am trying to retrieve.
#Entity
#XmlRootElement
public class Factory extends DomainEntity implements IHasSlots {
/**
* Serialization Id
*/
private static final long serialVersionUID = 7829467874878679280L;
private String name;
private List<Line> lines;
public Factory() {
this(null);
}
public Factory(String name) {
this(name, new ArrayList<Line>());
}
public Factory(String name, Collection<Line> lines) {
this(name, new ArrayList<Line>(lines));
}
...
This unit test always ends with an assert error that the list is empty.
#Test
public void testList() {
EntityManagerFactory emFactory = Persistence.createEntityManagerFactory("redis_pu");
EntityManager em = emFactory.createEntityManager();
List<Factory> factories = em.createQuery("SELECT e FROM Factory e").getResultList();
//Collection<Factory> factories = factoryDao.list();
Assert.assertTrue(factories.size() > 0);
}
