PostgresSQL Sauvegarde non effectuée

Bonjour,

Je me suis crée un objet 'Group'
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 public class Group<T> implements Comparable<Group<T>>, Serializable { /** Serial version UID */ private static final long serialVersionUID = 741587360128392267L; T holded; // Type of object holded by this group private String name; private String description; private List<T> items; // Constructeurs, accesseurs... }
Je voudrais persister cet objet sans la liste d'items..
Code:

1 2 3 4 5 6 7 8 9 10 <hibernate-mapping> <class name="be.me.Group" table="groups"> <id name="name" column="grpname"> <generator class="assigned" /> </id> <property name="description" column="grpdescription" /> <property name="holded" column="grptype" type="java.lang.String" access="field"/> </class> </hibernate-mapping>
Lorsque je lance l'exécution du code ci-dessous, je récupère bien les clef aprés sauvegarde mais jamais d'objet lorsque je veux en restaurer un et ma table reste vide. :
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 ApplicationContext ctx = new FileSystemXmlApplicationContext("applicationContext.xml"); DAOFactory daof = (DAOFactory) ctx.getBean("daoFactory"); GroupDao grpDao = daof.getGroupDao(); System.out.println( grpDao.saveGroup(new Group<Classe>("Technique")) ); System.out.println( grpDao.saveGroup(new Group<Classe>("Géneraux")) ); System.out.println( grpDao.saveGroup(new Group<Classe>("Langues")) ); System.out.println( grpDao.saveGroup(new Group<Classe>("Phylosophiques")) ); Group<Classe> group = (Group<Classe>) grpDao.getGroup("Technique"); if ( group!=null ) System.out.println( group.getName() +"\n"+ group.getDescription()); else System.out.println("Group is null");
Voici mes logs :

Group is null

Je ne vois pas ce qui cloche dans le jeux. Tout semble se passer correctement mais rien ne sinsère..

Edit 0 : Par contre un autre bean fonctionne très bien. Ne serais-ce pas à cause de l'id qui est une String ?
Edit 1 : Si j'entre à la main un clef dans la table tout se passe bien côté récupération.
