Note: in the case of an ItemCalculator whose ItemCalculator.Item has not been set, this property will return null even though the Infragistics.Calculations.Engine.CalculationValue.Value property returns an error. This is useful for situations where the item might be null e.g. in applications that allow the user to select the item but don't want to display an error in that scenario.
