For example: User loads AJAX slider order form Default package has blank quantity field (quantity is zero) The above requirements insist that any service with quantity zero not appear in the summary. This would prevent that item's configurable options from being shown in the order summary as well. I don't believe that is the desired behavior. According to CORE-1121 , any service with quantity of 0 will result in error when adding, so checkout is blocked. So, what, exactly, is the purpose and goal of not allowing items with 0 quantity through the Order plugin?
