GWT Validation Library / Discussion / Help: Exception with NameValidator

Ricardo García Laguía - 2010-01-20

Hello,

I'm perfectly using several validators but have an exception with a NameValidator defined like this:

PasswordTextBox new1Password;
validator.addValidators("pwdValidation",
new NameValidator(new1Password)
.addActionForFailure(new StyleAction("validationFailedBorder"))
.addActionForFailure(new LabelTextAction(errorLabel))
.addActionForFailure(new FocusAction()),
);

And I get the following:

I'll try to do it with a RegularExpressionValidator instead.

Hi Ricardo!

I think this is a bug that should have be taken care of in the snapshot version.

Please download the snapshot version and try again.

You can get it from here: http://gwt-vl.sourceforge.net/?to=resources

Anatol, thanks for your reply.

The link to the 0.9b-SNAPSHOT-without-hibernate version seems to be broken.

I've tried the NameValidator with the 0.9b SNAPSHOT version with hibernate but I get the same error:

Ok, I have uploaded a new snapshot version here: http://gwt-vl.sourceforge.net/?to=resources

Please get it and report back if that solves your issue.

Thanks

Hello Anatol,

The Namevalidator class works fine with gwt-validation-0.9b2-SNAPSHOT-without-hibernate.jar.

Glad to see spanish is now supported. I just point you a few details about the spelling:

validator_notNull=Debe introductirse
validator_email=Dirección de correo electrónio inválida
validator_creditCard=Numero de tarjeta incorrecto
notAValidCharacter = Cáracter inválido: ''{0}''
notAValidTimeWithoutSeconds = ''{0}'' no es un tiempo correcto (no se debe especificar los segundos)

should be:

validator_notNull=Debe introducirse
validator_email=Dirección de correo electrónico inválida
validator_creditCard=Número de tarjeta incorrecto
notAValidCharacter = Carácter inválido: ''{0}''
notAValidTimeWithoutSeconds = ''{0}'' no es un tiempo correcto (no se deben especificar los segundos)

Thanks for your help again.

Ricardo
