Hello, is this issue being solved.

I've seem to have a  similar problem.

Whatever I do, the error result is always the default generated message  ‘Name is Required’

Tried different verifiers.

Only a VerifierDelegate seems to work (I find a VerifierDeletage a bit overkill for just adding localization)

public class VerifierProvider : IVerifierProvider

{

   public IEnumerable<Verifier> GetVerifiers(Object pVerifierProviderContext)

   {   List<Verifier> verifiers = new List<Verifier>();           

       verifiers.Add(new RequiredVerifier("Contenttype required a unique name."));

       return verifiers;

   }

}

private class RequiredVerifier : RequiredValueVerifier

{

    public RequiredVerifier(string strMessage) : base( typeof(ContentType), ContentType.EntityPropertyNames.Name)

    {   this.VerifierArgs.ErrorMessageInfo.ErrorMessage = strMessage;

    }

}

public class MinLenghtStringVerifier : StringLengthVerifier

    {

        public MinLenghtStringVerifier(System.Type pType, string pProperty, string pMessage, int pMin, int pMax)

            : base(pType, pProperty, true, pMin, pMax)

        {

            this.VerifierArgs.ErrorMessageInfo.ErrorMessage = pMessage;

        }

    }
