Vaadin 8 Datefield - java-8

Question

How can i hide the immediate validation for the datefield in Vaadin 8 . I have the follwing code
dateField.setLocale(new Locale("fr", "CA"));
binder.forField(dateField).withValidator(new Validator<LocalDate>() {
#Override
public ValidationResult apply(LocalDate value, ValueContext context) {
if (LocalDate.now().equals(value)) {
return ValidationResult.ok();
} else {
return ValidationResult.error("the date is not the current date");
}
}
}).withValidationStatusHandler(new BindingValidationStatusHandler() {
#Override
public void statusChange(BindingValidationStatus<?> statusChange) {
if (statusChange.getResult().isPresent()) {
ValidationResult validationResult = statusChange.getResult().get();
if (validationResult.isError()) {
label.setCaption("the date is not the current date");
} else {
label.setCaption("the date IS the current date");
}
}
}
}).bind(CustomDate::getLocalDate, CustomDate::setLocalDate);
The result is however, that vaadin default validation (for example when the entered dateformat is not the expected format ) getting execued and my validation. I want to do the validation of the format expecitly in my validator. how to achieve that.

Answer 1

Maybe using setComponentError works for your use case. It should provide a way to override default error message.
For examples, see Handling Errors.

I did not try it but you can check if it works as described in the documentation (here):
DateField date = new DateField("My Date") {
#Override
protected Result<LocalDate> handleUnparsableDateString(
String dateString) {
try {
// try to parse with alternative format
LocalDate parsedAtServer = LocalDate.parse(dateString, DateTimeFormatter.ISO_DATE);
return Result.ok(parsedAtServer);
} catch (DateTimeParseException e) {
return Result.error("Bad date");
}
}
};
According to documentation, client-side validation can be hidden via CSS.
