VerifierEngine.Execute

may satisfy

   When I run VerifierEngine.Execute(Entity x) the verifier collection returned doesn't include my custom verifiers. I can step through and watch them run but the are not in the collection returned. It only includes the foreign key constraint verifiers. Why is that? I have tried using the generic EntityModel.Entity and the specific Contact when running execute.
Implementation on DXGrid Row or Column Verification:

VerifierEngine engine = new VerifierEngine();

engine.DiscoverVerifiers(e.Row.GetType());
VerifierResultCollection verifiers = engine.Execute((EntityModel.Entity)e.Row);

public partial class Contact : BaseEntity 
  {
      #region Verification

      /// <summary>
      /// Implement IVerifierProvider interface to give DevForce the verifiers in use at run time.
      /// </summary>
      public class VerifierProvider : IVerifierProvider
      {

          #region IVerifierProvider Members

          public IEnumerable<Verifier> GetVerifiers(object verifierProviderContext)
          {

              List<Verifier> verifiers = new List<Verifier>();
              verifiers.Add(FirstNameRequiredVerifier());
              verifiers.Add(LastNameRequiredVerifier());
              return verifiers;
          }

          #endregion
      }

      private static Verifier FirstNameRequiredVerifier()
      {
          Verifier v = new DelegateVerifier<Contact>("First Name is required", MinLengthCondition);
          v.VerifierOptions.ExecutionModes = VerifierExecutionModes.OnBeforeSetTriggers;
          v.AddTrigger(new TriggerItem(typeof(Contact), Contact.PropertyMetadata.FirstName.Name));
          return v;
      }

      private static Verifier LastNameRequiredVerifier()
      {
          Verifier v = new DelegateVerifier<Contact>("Last Name is required", MinLengthCondition);
          v.VerifierOptions.ExecutionModes = VerifierExecutionModes.OnBeforeSetTriggers;
          v.AddTrigger(new TriggerItem(typeof(Contact), Contact.PropertyMetadata.LastName.Name));
          return v;
      }

      private static VerifierResult MinLengthCondition(Contact pContact, TriggerContext triggerContext, VerifierContext verifierContext)
      {
          bool pass = (triggerContext.ProposedValue != null && triggerContext.ProposedValue.ToString().Length > 0);
          return new VerifierResult(pass);
      }
      #endregion
