Die Rollen Klasse muss soweit ich weiss auch das Serializable Interface Implementieren.
Wie werden die Id's in der Rollen Klasse gehandhabt? bzw. wieso benutzt du keine automatische Generierung dort wie in Person?

lass dir korrekte getter/setter zu deinem id Attribut generieren.

die müssten so aussehen:

Code:
   /**
    * @return the idRoles
    */
   public Integer getIdRoles() {
      return idRoles;
   }

   /**
    * @param idRoles the idRoles to set
    */
   public void setIdRoles(Integer idRoles) {
      this.idRoles = idRoles;
   }

rolesGUI ist sozusagen die Liste mit den Rollen ?
Wenn ja könntest du folgendermaßen z.B. vorgehen
Code:
for (Iterator iter = rolesGUI.iterator(); iter.hasNext();) {
           rolesGUI element = (rolesGUI) iter.next();
                roles.add(element);
       }


Ein andere Ansatz wäre es eine findby query anzulegen und die Rollen (wenn ich es richtig verstanden hab sind diese fest definiert und in de rDatenbank hinterlegt) bevor du sie zuordnest herrauszulesen.

So vielleicht?
Code:
for (Iterator iter = rolesGUI.iterator(); iter.hasNext();) {
           (SelectItem) element = ((SelectItem)) iter.next();
                roles.add(element);
       }

Du könntest den zweiten Parameter von find durch den Schleifenzähler ersetzten. Weiss aber nicht ob der erwartete Wert ein Integer sein muss?
So ungefähr -> Wenns nichts geht dann halt durch einen integer ersetzten.

Code:
for (Iterator iter = rolesGUI.iterator(); iter.hasNext();) {

Role element = entityManager.find(Role.class, iter);
roles.add(element);
       }

jedoch ist mein schleifenzähler ja nicht meine echte idRole sondern nur mein Schleifenzähler...
