Return empty result list - Composed primary key - lucene search ok - primary key bridge ok
------------------------------------------------------------------------------------------

Entity :

@Indexed
@Entity
public class Demande extends DemandeEntity {
...

Superclass :

...

@MappedSuperclass
public class DemandeEntity implements Serializable {

   ...

   @FieldBridge(impl=Demande_DocumentId_Bridge.class)
   @DocumentId
   @IndexedEmbedded
   private DemandePK demandePK;

   ...

Bridge :

...

public class Demande_DocumentId_Bridge implements TwoWayStringBridge {

   ...

   public Object stringToObject(String arg0) {
      String[] tab = arg0.split("þ");
      return new DemandePK(tab[0],tab[1],tab[2]);
   }

   ...

   public String objectToString(Object arg0) {
      DemandePK d = (DemandePK)arg0;
      return d.getUiPhar()+"þ"+d.getRdes()+"þ"+d.getTypeDem();
   }
}

TestClass :

...

public static void main(String[] args) {
      
      ClassPathXmlApplicationContext appContext = new ClassPathXmlApplicationContext("META-INF/PostGreSQL-applicationContext.xml");
      GenericSearchManagerMetier demandeSearchManagerMetier = (GenericSearchManagerMetier) appContext.getBean("demandeSearchManagerMetier");
      
      String rqt = "+text:jean +text:francois";
      BeanLuceneQuery beanLuceneQuery = new BeanLuceneQuery(rqt);   
      BeanResultats br = null;
      
      try {
         br = demandeSearchManagerMetier.searchLuceneQuery(beanLuceneQuery,0,15);
      } catch (NegativeOrNullInteger e) {
         e.printStackTrace();
      }
      
      System.out.print("Nb total : "+br.getNbTotalResults()+"\n");
      System.out.print("Nb Résultats : "+br.getResults().size()+"\n");
      
   }

Lucene part of process is alright !
Primary keys DemandePK generated by HS just before requesting DB are alright

but no return...

br.getNbTotalResults() return 16
but
br.getResults().size() return 0

Beans are correctly implemented.
I traced return of :

List<T> resultList = q.getResultList();

but list size = 0

stdout :

...

Hibernate: select this_ (..xxx..)  from Demande this_ where ((this_.RDES, this_.TYPE_DEM, this_.UI_PHAR) in ((?, ?, ?), (?, ?, ?), (?, ?, ?), (?, ?, ?), (?, ?, ?), (?, ?, ?), (?, ?, ?), (?, ?, ?), (?, ?, ?), (?, ?, ?), (?, ?, ?), (?, ?, ?), (?, ?, ?), (?, ?, ?), (?, ?, ?)))
Nb total : 16
Nb Résultats : 0
