When placing an order, the articles remain in the cart, while the order stays in 'Processing' state

[lmeyer1]

Describe the bug
When placing an order, after confirming the order, the articles of the order are still in the cart.

To Reproduce
Steps to reproduce the behavior:

1. Put an article into the cart
2. Place an order, selecting Postfinance Card as payment method
3. Click on the first button I confirm my order.
4. Notice that the order is complete and that the cart still contains the same article
5. Log into the BO
6. Go to the list of the orders
7. Notice that the order is in Postfinance Checkout Processing state

Expected behavior
After placing an order, the cart must be empty

Screenshots
Order is complete, but cart still contains the ordered article:

The order remains in Postfinance Checkout Processing state

Software versions (please complete the following information):

• Prestashop: 1.6.1.24, fresh install, default demo data.
• Postfinance Checkout: 1.2.17, latest version as of today, with PR Fix error: Cannot read properties of undefined (self). #3 applied
• PHP: 7.1.32

Additional information

This is how to set up the test installation:

• Get XAMPP Version 7.1.32 portable
• Unzip Prestashop 1.6.24 in C:\xampp\htdocs\prestashop-1.6.1.24
• In phpmyadmin create a database and a user
• Install Prestashop the standard way, choose Switzerland as a country
• In the BO, got to Transport - Carriers and activate the zone Europe non-EUfor shipping (This is necessary to be able to place orders from Switzerland, we installed Switzerland).
• Install the latest version of Postfinance Checkout (currently 1.2.17)

When applying #11, the state of the order evolves to become Postfinance Checkout Authorized and then Payment accepted.
Nevertheless, the main problem still remains: When placing an order, the articles remain in the cart (or a new cart is created with the same articles in it).

Dear lmeyer1

Sorry for the late response.

Is this issue still relevant for you?

[lmeyer1]

As explained here #9 (comment) this question comes too late.

Of course your mess is not working at all. Of course I lost hundreds of hours with it.
But I don't care anymore if you fixed something since then

@theodorspringwallee
You closed this issue as Fixed, what is not true. It would have been more honest to close it as Won't fix, wouldn't it ?
