XStream - Modifier des champs XML
Bonjour,
L'objectif de mon projet et de charger un XML, compléter des input text avec les valeurs lues dans le XML afin de pouvoir les modifier, et generér un nouveau fichier XML ainsi modifié (actuellement pas de génération mais affichage dans une fenetre de dialog). J'utilise JSF et Primefaces et actuellement je peux lire un XML, compléter les input text, mais lorsque je veux générer le nouveau xml avec les modifications, soit la fenêtre de dialog est vide, soit elle affiche les anciennes valeurs. Merci de bien vouloir trouver ci après mon code :

Si un développeur sait m'aider ce serait sympa, j'essai de trouver une solution depuis mercredi dernier.
Cordialement.
