Hi,

I would like to report bug in CalculateOrderLineTaxRateTask.

When price is equal to 0, this task throws DivideByZeroException.

I have fixed this issue by overriding this task as below, but I hope this will be fixed in following versions.

public class newCalculateOrderLineTaxRateTask : UCommerce.Pipelines.IPipelineTask<PurchaseOrder>
{
    public PipelineExecutionResult Execute(PurchaseOrder subject)
    {
        foreach (OrderLine orderLine in (IEnumerable<OrderLine>)subject.OrderLines)
        {
            if (orderLine.Price == 0)
            {
                orderLine.VATRate = 0;
            }
            else
            {
                Decimal num = Decimal.Round(orderLine.VAT/orderLine.Price, 4);
                if (Math.Abs(orderLine.VATRate - num) > new Decimal(5, 0, 0, false, (byte) 3))
                    orderLine.VATRate = num;
            }
        }
        return PipelineExecutionResult.Success;
    }
}

I'm using uCommere 7.0.0.16029
