Surcharges multiples classes js du POS openerp
Bonjour à tous,
(Config : openerp 7 sur ubuntu)
j'ai un souci concernant la surcharge de la classe Backbone.Model dans le fichier models.js du POS
En fait, je surcharge cette classe pour pouvoir recupérer un champ que j'ai ajouter dans le modèle product.product, pour pouvoir l'afficher sur les produits comme c'est fait actuellement avec le prix de vente. Voici le code de mon fichier models.js dans lequel j'effectue la surcharge :

Le problème c'est que il y' a un autre module installé qui surcharge le même modèle. Voci le code du fichier models.js de ce module :
Donc pour résumer, au chargement du POS, les 3 fichiers sont chargés dans l'ordre :

1-) models.js original
2-) models.js de l'autre module
3-) models.js de mon module
ce qui est bizarre c'est que meme si mon fichier est chargé en dernier, le champ que j'ai ajouté est écrasé par la surcharge de l'autre module et sur le POS on lit un 'undefined' à la place de mon champ.
Mes questions :
1-) Existe t -il un moyen d'empecher le chargement d'un fichier provenant d'un autre modules?
2-) Est-ce la bonne manière de surcharger une classe en js? cette méthode marche mais le problème c'est que je réecris totalement la classe en y ajoutant ma modif ce qui me parait assez lourd. et en plus cette classe est de ce fait appelée 3 fois
Je tiens déja à vous remercier si vous avez lu jusqu'ici(pas grand monde ne l'a fait à mon avis) et j'espère que vous pourrez m'apporter des solutions.
Cordialement,
