Seam problem with SelectOneMenu

[lbertrand]

Hi,
I think I've a big problem with understanding Seam.
I'm trying to make a simple new user form, but I'm on the wrong way I think, because it doesn't work :

I've a User entity class :

@Entity
@Name("user")
@Table(name = "user", catalog = "mydb")
public class User implements java.io.Serializable {
 
     private int uCode;
     private UserType userType;
     private String uFirstname;
     private String uLastname;
     private String uPhone;
     private String uEmail;

then getters and setters...

I've a UserType entity class :

@Entity
@Name("userType")
@Table(name = "usertype", catalog = "mydb")
public class UserType implements java.io.Serializable {
 
     private int utCode;
     private String utName;
then getters and setters...

I have also a Session bean which manages my page :

@Stateful
@Name("userBean")
@Scope(ScopeType.SESSION)
public class UserBean implements IUser {
 
     @In(required=false)
     @Out(required=false) 
     User user;
     
     @DataModel
     private List<User> users;
     
     @PersistenceContext
     EntityManager entityManager;
     
     public String add()
     {
            em.persist(user);
        }
}

and finally, here is my view :

<!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
                      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <h:form>
         <table border="0" width="600px">
         <tr>
              <td>#{messages.lastname} :</td>
              <td><h:inputText value="#{user.uLastname}" /></td>
         </tr>
         <tr>
              <td>#{messages.firstname} :</td>
              <td><h:inputText value="#{user.uFirstname}" /></td>
         </tr>
         <tr>
              <td>#{messages.usertype} :</td>
              <td>
                   <h:selectOneMenu value="#{user.userType}" >
                        <s:selectItems value="#{allusertypes}" var="type" label="#{type.utname}"  />
                        <s:convertEntity  />
                   </h:selectOneMenu>
                   
              </td>
         </tr>
         <tr>
              <td>#{messages.email} :</td>
              <td><h:inputText value="#{utilisateur.utemail}" /></td>
         </tr>
         <tr>
              <td>#{messages.phone} :</td>
              <td><h:inputText value="#{user.uPhone}" /></td>
         </tr>
         </table>
         <h:commandButton action="#{userBean.add}" value="Ok" type="submit"  ></h:commandButton>
    </h:form>
    </rich:panel>
</ui:define> 
</ui:composition>

The main problem concerns the selectOneMenu, because I can't get the UserType value in my User Entity, and I have
this kind of error in my Eclipse Console :

INFO  [lifecycle] WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.
sourceId=j_id49:j_id57[severity=(ERROR 2), summary=(j_id49:j_id57: Erreur de validation: Valeur not valid.), detail=(j_id49:j_id57: Erreur de validation: Valeur not valid.)]

Could someone help me please ?
