public Guid InventoryPK

get
{
if (this.Row != null)
return (Guid)mmType.GetNonNullableDbValue(this.Row["InventoryPK"], "System.Guid");
else
return this._inventoryPK;
}
set
{
if (this.Row != null)
this.Row["InventoryPK"] = value;
this._inventoryPK = value;
}
}
private Guid _inventoryPK;

The problem comes in if I check to see if a value has been assigned. If the row has been created and nothing has been assigned, I get an error that it can't cast null to the Guid. In this instance, I can set the default when the row is created. In other circumstances, there really isn't a default.
