I have a problem with the basket controller. In my project i am using the code from bazaar's basket controller. It throws an error when saving the basket. I have added Merchello source to the project and it throws the exception in the CustomerContext class, in this method:

protected override void EnsureCustomerCreationAndConvertBasket(ICustomerBase customer)
        {
            if (!customer.IsAnonymous) return;

            var memberId = Convert.ToInt32(this.MembershipProviderKey(customer.Key));
            var member = _memberService.GetById(memberId);

            if (MerchelloConfiguration.Current.CustomerMemberTypes.Any(x => x == member.ContentTypeAlias))
            {
                base.EnsureCustomerCreationAndConvertBasket(customer);
            }
        }

memberId=-1, so member=null and throws a null exception.

I have created a "Customer" membertype. I dont know if i have to configure something else, maybe in merchello.config?
