private final int maxlen;
public void boolean validate(IValidatable<String> validatable) {
if (!Strings.isEmpty(validatable.getValue ())&&validatable.getValue().length>maxlen) {
ValidationError error=new ValidationError(MaxStringLenValidator.class.getName());
error.addParam("maxlen", String.valueOf (maxlen));
validatable.error(error);
}
}
}
implementation of validationerror is left as an excercise to the reader.
the only thing i am not sure about yet is how to best work in ${label} since the error is now in charge of generating the error message - maybe that can be done inside the localizer even though its a bit outside the context of localization - maybe there should be a better name then localizer then

Could you give an example of how you would use it/ how does this play
