Hello. I have a form with a business object and it keeps giving me a null reference error. All fields are set to values, but when I try to save the business object it keeps giving me a null reference error.

Private _unit As Unit
Me._unit = CType(Me.RegisterBizObj(New Unit), Unit)

Me._unit.NewEntity()
Me._unit.Entity.Code = currentLine(1).Substring(4, 3)
Me._unit.Entity.Name = currentLine(2).Substring(6, currentLine(2).Length - 6)
Me._unit.Entity.LastUpdateDate = DateTime.Now
Me._unit.Entity.LastUpdateUser = Environment.UserName
Me._unit.Entity.Active = True
Me._unit.SaveEntity()

Thanks.
