I found a little issue on handling coupons in cart.
To reproduce this issue you have to do:
- create three simple products
- create a cart rule with coupon
- assign conditions, so that sku of product 1 and product 2 will match the coupon
- add product 1 to cart
- add product 2 to cart
- last add product 3 to cart (which has no coupon matching)
- apply the coupon
You get an error message.
So therefore I made some little changes.
