[JSF - RichFaces] SelectOneMenu & NoSuchElementException
Bonjour à tous,
Dans mon formulaire, j'ai un système de filtre de liste déroulante.
Je vous explique :
* J'ai une liste déroulante (businessPartnerType), lorsque je sélectionne un élément, une autre liste déroulante (businessPartner) est filtré en fonction du choix de la première liste.
Mon problème est que :
* Lorsque je valide mon formulaire, et que je n'ai pas touché aux 2 listes déroulante, celui-ci ne génère aucune exception.
* Par contre lorsque je sélectionne dans ces liste déroulante et que je valide mon formulaire, une exception du type NoSuchElementException est lancé.
Voici mon code :
* form.xhtml
