Que faire ? Si je ne résouds pas cette erreur je ne peux pas aller plus loin, mon programme tourne mais mal.

Auriez-vous des pistes ?

Eh bien, tu as une ClassCastException, probablement due au fait que tu essaie de comparer des objets de types différents.
Sans code, ça va être difficile d'en dire plus.

Merci,

oui je n'ai pas posté mon code car je voudrais pas diffuser tout mon projet, c'est pour une entreprise.

Mais je peux vous l'envoyer par mail si vous voulez, le problème c'est qu'en message privé je peux pas joindre de fichiers....

Ou alors tu peux joindre juste la portion de code incriminée en maquillant les choses que tu ne veux pas montrer.

Mon projet est trop gros pour le joindre sur le forum
et je doute que ne joindre que quelques pieces ne suffise pour comprendre..
mais si vous me donnez votre mail par message privé je vous le joint..

merci!

[wilfryjules]

Il n'y a personne à qui je pourrais joindre mon projet? Pour qu'il y jette un oeil?

Dès le lancement, il y a des CastExceptions, et j'ai 20 000 fenêtres écrasées qui s'ouvrent....
