Hello,

Using Umbraco Forms 4.1.4 what is the best practice for developing an field type that has multiple inputs ?

I have a custom field type, with three inputs (in this example its day, month year) and i want to merge them into a single (date) field.

in the FieldType class I have Overrriden ProcessSubmittedValue to merge the three fields into one and return that in the vals object.

public override IEnumerable<object> ProcessSubmittedValue(Field field, IEnumerable<object> postedValues, HttpContextBase context)
{
    LogHelper.Info<SimpleDatePicker>("ProcessSubmittedValue");

    var vals = new List<object>();

    var day = int.Parse(context.Request["dob-day"].ToString());
    var month = int.Parse(context.Request["dob-month"].ToString());
    var year = int.Parse(context.Request["dob-year"].ToString());

    var date = new DateTime(year, month, day);

    vals.Add(date);

    return vals; 
}

on submit this gets called and the value does get submitted - i can see that in the form entries.

however when i set it to mandatory, the validation fails - the JQuery validation passes - it appears to fail on the server side.

I have overriden ValidateFeilds . with the below.

public override IEnumerable<string> ValidateField(Form form, Field field, IEnumerable<object> postedValues, HttpContextBase context)
{
    LogHelper.Info<SimpleDatePicker>("Validate Field? {0}", () => field.Alias);

    if ( field.Values != null && field.Values.Any() )
    {
        LogHelper.Info<SimpleDatePicker>("Validate Has Values");
        var date = (DateTime)field.Values.First();
        return new List<string>();
    }

    LogHelper.Info<SimpleDatePicker>("Passing to base");
    return base.ValidateField(form, field, postedValues, context);
}

but looking in the logs, i never get to "Has Values" -

Do i access the values via context like i have done in the ProcessSubmit ? or am i missing something to get the values in the Field.Values for validation ?
