@mykehsd this is the source of failing tests. You added this in the form but didn't adjust the generation form. This is not the same as the coupon form, it's a form with parameters to generate a bunch of coupons. You can't add a user reference in PromotionBundle, so I suggest you to simply delete this line for now (leading to generate coupons with "0" as perUserLimit). We'll add this field to the generation form later.
