Coupon one item only

[jerome_vtf]

Hello everyone,

I'm facing a problem and can't find a way to get out of it so I'm going to request some of your help please...

Actually, I set up a coupon in the zencart admin and I set up restrictions as followed :
Categories => top - deny
Products => myproduct - allow

But when time comes to order, my coupon applies to every order no matter "myproduct" is placed or not into the cart...

My use case is actually simple :
I want two products, "myproduct" and "otherproduct". The coupon should only apply on "myproduct" and not on the whole order.
if "myproduct" costs 20 and "otherproduct" costs 50 then my coupon is 50% off (percentage), I should pay "10 + 50" and not "20+50".

But instead of this, I got "(20+50) * 50%", it applies on the whole order...

Is there a way to change this or is there a bug ?

My ZNC config : 1.3.9d
