MVC 3 Razor - ICollection Validation Issue

Juan Bengoa asked:

I'm trying to validate a dynamically generated Radio Button Groups for a Survey that the answers and questions are dynamically generated too, but when I try to submit the form the validator message appears but isn't functioning right because I'm making a mistake with the jQuery implementation or the method of validation.

I want to validate (unobstrusive) each answer by question generated in the form after submit, like the other field's (CodChofer, CodUsuario).

I have this model:

[Table("Encuesta")]
    public class Encuesta
    {
        [Key]
        public int IdEncuesta { get; set; }

        [Required(ErrorMessage = "El código del chofer es requerido.")]
        [Display(Name = "Código de chofer")]
        [MaxLength(7, ErrorMessage = "Código de chofer debe ser de máximo 7 dígitos.")]
        [MinLength(7, ErrorMessage = "Código de chofer debe ser de mínimo 7 dígitos.")]
        public string CodUsuario { get; set; }
        [Required(ErrorMessage = "El código de usuario es requerido.")]
        [Display(Name = "Código de usuario")]
        [MaxLength(7, ErrorMessage = "Código de usuario debe ser de máximo 7 dígitos.")]
        [MinLength(7, ErrorMessage = "Código de usuario debe ser de mínimo 7 dígitos.")]
        public string CodChofer { get; set; }

        public virtual ICollection<Pregunta> Preguntas { get; set; }
        [MultipleRequiredValues(ErrorMessage = "Debe elegir una respuesta por pregunta")]
        public virtual ICollection<Respuesta> Respuestas { get; set; }

        public string Observaciones { get; set; }

        [ReadOnly(true)]
        [DataType(DataType.Date)]
        public DateTime Fecha { get; set; }

        [ReadOnly(true)]
        public int Puntuacion { get; set; }

        public Encuesta()
        {
            this.Fecha = DateTime.Now;
        }
    }

I have this custom validator:

namespace SSU.DAL.Validators
{
    [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = true)]
    public class MultipleRequiredValuesAttribute : RequiredAttribute, IClientValidatable
    {
        #region IClientValidatable Members

        public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
        {
            var clientValidationRule = new ModelClientValidationRule()
            {
                ErrorMessage = base.ErrorMessage,
                ValidationType = "multiplerequiredvalues"
            };

            return new[] { clientValidationRule };
        }

        #endregion
    }
}

When answering a question please:

Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.
If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem. Insults are not welcome.
Don't tell someone to read the manual. Chances are they have and don't get it. Provide an answer or move on to the next question.

Let's work to help developers, not make them feel stupid.
