Bonjour,

Dans une application que je développe, j'ai le message d'erreur suivant :

Quelqu'un saurait-il m'indiquer comment résoudre ce problème ?

Merci d'avance pour votre aide.

Tu as a vérifié que le paramètre 'adherent' est bien initialisé dans ton controleur?

Tu as a vérifié que le paramètre 'adherent' est bien initialisé dans ton controleur?

oui je verifie

[QuentP]

Essaie avec cette signature de méthode peut-être :
private ModelAndView prepareModelAndView(@ModelAttribute Adherent adherent )

http://docs.spring.io/spring/docs/4....attrib-methods

[footsteps]

Une fois que tu appelles ta méthode (dans le controller) correspondante au formulaire post,il faut que relances ton model.addAttribute("",new ton objet()ici adherent) sinon la page affichée après avoir réalisé le traitement,ne contiendra plus ton champ de formulaire vide.
Erreur classique mais qui m'arrive souvent.
