qui m'interpelle, je peux me tromper.
A force de chercher, je pense que j'ai fini par isoler la source du problème, qui semble être l'attribut data. si je remplace
Code:
oncomplete="if (data != -1) { document.location.href = ('#{facesContext.externalContext.requestContextPath}/client/Ecr_Cli_2.seam?idClient=' + data); } else { refreshMessages(); } "
par
Code:
oncomplete="if (data != -1) { document.location.href = ('#{facesContext.externalContext.requestContextPath}/client/Ecr_Cli_2.seam?idClient=' + 1); } else { refreshMessages(); } "
alors ça fonctionne.
Quelqu'un pourait-il me faire une suggestion pour régler le problème? Et éventuellement m'expliquer ce qui se passe, je serais curieux de savoir pourquoi data me transforme un int en (je suppose) une string.
Merci d'avance.
