Actualiser les items d'un selectOneMenu sur un onchange d'un autre selectOneMenu

**Glopp** · 13/01/2010, 01h53

Salut,

Voila j'ai deux selectOneMenus, un pour une liste de catégories, un autre pour une liste de sous-catégories et j'essaie de rafraichir et filtrer ma liste de sous-catégories à la sélection d'une catégorie.

J'arrive bien a lancer ma méthode refreshSubTypeList() mais ma liste de sous-catégorie n'est pas actualisée.
