Prestashop: Products with combination

Created on 10 Oct 2018 · 4Comments · Source: PrestaShop/PrestaShop

Describe the bug
The problem happen when there is a product with combinations and every combination has a minimun quantity order quantity.
When you are in the frontend product page, for instance if you choose a combination with minimun order quantity 200 the quantity input field is updated to 200 correctly (see image attached minimum_quantity_200.PNG), after this if you choose again a combination with minimum order quantity lower then the previous (for instance 100) the input field remains 200 (see attachment minimum_quantity_100.PNG).
This isn't the real problem indeed, if you try to change manually the input field setting for instance 100, it's impossible do add the product to the cart; clicking on the button "Add to cart" will get no action at all (see image attached minimum_quantity_100_B.PNG).
This is due to the fact that for the page the minimum order quantity is still set to 200.

To Reproduce
Steps to reproduce the behavior:

Go to a product page with combination that have different minimum order quantity
Click on a combination with minimum order quantity for instance 200, after choose a product with minimum order quantity setted to 100 and update manually the input field quantity to 100.
In this situation it's impossible to add the combination to the cart.
