SQL view works in Query Analyzer, but I get an error that a field does not exist

I have a SQL View that returns data when I run a select statement in SQL Query Analyzer.  I get an error that the CustomerLocationID field does not exist when I try to access the DAC.

If I remove that field, it works fine.  But I need that field.

This is the DAC

    #region SOShipment
	[Serializable]
	[PXCacheName("SOShipment SQL View")]
	public class ICSSOShipmentSQLView : IBqlTable
	{
		#region CustomerID
		[PXDBInt]
		public virtual int? CustomerID { get; set; }
		public abstract class customerID : PX.Data.BQL.BqlInt.Field<customerID> { }
		#endregion

		#region CustomerLocationID
		[PXDBInt]
		public virtual int? CustomerLocationID { get; set; }
		public abstract class customerLocationID : 
          PX.Data.BQL.BqlInt.Field<customerLocationID> { }
		#endregion

		#region ShipmentNbr
		[PXDBString(15, IsUnicode = true, IsKey = true)]
		public virtual string ShipmentNbr { get; set; }
		public abstract class shipmentNbr : PX.Data.BQL.BqlString.Field<shipmentNbr> { }
		#endregion
	}

This is the SQL View 

CREATE VIEW [dbo].[ICSMCSOShipmentSQLView]
AS
SELECT    
	CustomerID, 
	ShipmentNbr,
	CustomerLocationID
FROM            
	dbo.SOShipment
GO

When I execute SELECT * FROM [ICSMCSOShipmentSQLView] I get data in that field.

In debug, when this line fires I get an error:

foreach (ICSSOShipmentSQLView reg in SelectFrom<ICSSOShipmentSQLView>.Where<ICSSOShipmentSQLView.customerID.IsEqual<@P.AsInt>>.View.Select(this, item.FromCustomerID))
					{
  string test = "testing";
}

I’ve tried deleting the View in Query Analyzer, as well as EXEC sp_RefreshView ICSMCSOShipmentSQLView.  

The SOShipment table shows the CustomerLocationID as nullable, int.  That is how my DAC is setup too.

I checked and there are no records in that table with a null value in the field, so that is not it.

To reiterate, if I remove that field from the DAC, there is no error.

What am I doing wrong?
