When I run this test: 
[TestMethod]

public void AddABogusDealNoLastUpdated()

{

    Deal deal = Deal.Create(); 

    deal.LastUpdateUser = "";

    //next line should throw verifier error without LastUpdateUser

    IdeaBlade.EntityModel.SaveResult result = deal.EntityAspect.EntityManager.SaveChanges();

}

The [Required] attribute on the LastUpdateUser property doesn't seem to be doing much.
My savehandler does this: 
public void DomainModelEntityManager_Saving(object sender, IdeaBlade.EntityModel.EntitySavingEventArgs e)

{

    VerifierResultCollection allResults = new VerifierResultCollection();

    foreach (Entity item in e.Entities)

    {

        var itemResults = ((BaseEntity)item).VerifyInstance();

        foreach (var result in itemResults) { allResults.Add(result); }

    }

    if (!allResults.AreOk)

    {

        e.Cancel = true;

        VerifierResults = allResults;

    }

}

I have a verifier that checks something else and it causes the save to be canceled. I had assumed that the [Required] field being empty would be a problem, but instead I get an Oracle error:
IdeaBlade.EntityModel.EntityManagerSaveException: ORA-01400: cannot insert NULL into ("GCSD9"."DEAL"."LAST_UPDATE_USER")
ORA-06512: at line 4 ---> Devart.Data.Oracle.OracleException: ORA-01400: cannot insert NULL into ("GCSD9"."DEAL"."LAST_UPDATE_USER")
ORA-06512: at line 4.

Is there a way to verify that the [Required] fields are populated?

What does your Create method look like? Are you initializing any fields in there to null?

Yes. I do. Here is the code: 
public static Deal Create(User user)

{

     return (Deal)Create<Deal>(user);

}



protected static BaseEntity Create<T>(User user) where T : BaseEntity

{

     InitManager();

     T item = _manager.CreateEntity<T>();

     GetATemporaryKey(item);

     item.InitializeDefaults(user);

     AddToManager(item);

     return item;

}



protected override void InitializeDefaults(User user)

{

     this.EnteredBy = user.UserId;

     this.DateEntered = DateTime.Now;

     this.DateOfDeal = DateTime.Today;

     this.DealNumber = null;

     this.Promoted = false;

     this.SoftDeleted = false;

     this.DealTermsChanged = false;

     this.Delivered = false;

     this.FlowDateStart = DateTime.Today.AddDays(1);

     this.FlowDateEnd = DateTime.Today.AddWeekdays(1);

}

Are you using .NET or DevForce validation? Are you decorating the property with a [Required] attribute (.NET's) or [RequiredValueVerifier()] (DevForce's)?

I switched from .Net to IdeaBlade validation and the RequiredValueVerifier is now there and working. Thank you. That fixed it. My Test now passes: 
[TestMethod]

[ExpectedException(typeof(IdeaBlade.Validation.VerifierResultException))]

public void AddABogusDealNoLastUpdated()

{

     Deal deal = Deal.GetASimpleBuyDeal();

     deal.LastUpdateUser = "";

     //next line should throw error without LastUpdateUser

     IdeaBlade.EntityModel.SaveResult result = deal.EntityAspect.EntityManager.SaveChanges();

}
