Unable to continue with payment of order when pressing "back" to payment selection

[karl-ravn]

When an order

Steps to reproduce

1. Install Magento from develop branch.
2. Add Product to the cart.
3. Install (for instance) SaferPay plugin from CustomWeb
4. Go to Checkout
5. Fill in shipment details
6. Select payment method and click "Place order"
7. Press back in button (not cancel in payment provider)
8. Press "Place order" again

   Expected result

9. You would go to the payment provider and continue on the already made order in the system

   Actual result

10. You get an error due to that the database table sales_order already contains the increment number
11. The order is now in "pending payment" state until the timeout occurs, and the user cannot proceed with checkout without clearing cookies or switching web browser.

@karl-ravn , seems your problem not related to Magento functionality and relates to SaferPay plugin. If this behavior is reproducible with other Magento built-in payments, please, update details and reopen this issue.

In other case, please refer to the Community Forums or Magento Stack Exchange site for technical questions.

Seems to be same problem as #4580

[karl-ravn]

The problem seems to be that the quote has been created with a reserved_order_id, but there already exists a row with the same increment_id in order_sales.

The error goes through: OrderManager#save(\Magento\Sales\Api\Data\OrderInterface $entity) OrderService#place(\Magento\Sales\Api\Data\OrderInterface $order) QuoteManagement#submitQuote(QuoteEntity $quote, $orderData = []) (line 478 Magento 2.0.5 $order = $this->orderManagement->place($order);)

This could be avoided if either QuoteManagement#submitQuote() or Quote#reserveOrderId() would do a sanity check that there are no order with a conflicting increment_id. If a conflict is found, just regenerate a new order id.

We just had this exact issue on Magento 2.07 using Braintree as our payment provider. Same steps to replicate the issue and since it was for a registered user, we had to manually remove the quote in the DB in order to allow them to create a new cart for checkout.

Anyone figured out a temp fix?

I'm having the same issue.

@bvboas as stated in https://github.com/magento/magento2/issues/4580 , commit https://github.com/magento/magento2/commit/fe97d9e4540741edb0abc876d169c1df60a06b70 should fix the issue. I didn't test it myself, but I'm looking into it as well.
