Customize the checkout flow is emptying the cart

[ighor]

I want to remove the addreess and delivery steps but if I do using the checkout_flow helper like this:

Spree::Order.class_eval do
  checkout_flow do
    go_to_state :payment, if: ->(order) {
      order.update_totals
      order.payment_required?
    }
    go_to_state :confirm, if: ->(order) { order.confirmation_required? }
    go_to_state :complete, if: ->(order) {
      (order.payment_required? && order.has_unprocessed_payments?) || !order.payment_required?
    }
  end
end

Or like this:

Spree::Order.class_eval do
  remove_checkout_step :address
  remove_checkout_step :delivery
end

When I checkout a non empty cart, inside the CheckoutController#edit, the line_item is being deleted and I can't figure out why. Then it redirects to the cart instead of payment step and shows a empty cart.

Just saw that this is related to issues #2966 and #3142

The method before_payment in CheckoutController is the responsible to delete the line_items.

another reminder something needs to be done about #3193

Given that #3193 is fixed now, I'm going to assume that this issue is fixed too.
