Conserver les valeurs d'éléments Set dans un POJO
Bonjour,
J'ai une classe POJO qui a des éléments Set :

L'id correspond à un champs auto_increment dans ma BDD
J'ai un formulaire dont les champs correspondent à cette classe.
Pour les Set il s'agit de multiple select.
Si je fais une erreur dans mon formulaire(par ex : oublier un champs obligatoire), le validator me retourne le formulaire avec les données des champs du device(userAgent, manufactuerName) mais tous les éléments multiple select qui correspondent aux Set sont vidés.

Comment faire pour qu'il me garde les valeurs sélectionnées dans mes multiple select si le formulaire est réaffiché pour des erreurs(ex: champs obligatoire incomplet)
