[2.1.0] In Stock/Out of Stock state not updating when changing quantity of item

[peec]

When changing the quantity of a product from any number to 0, the state is automatically changed to Out of Stock upon saving. However, when changing an out of stock product to any number and saving, the product is still listed as Out of Stock.

Steps to reproduce

1. Access an active, out of stock product through Products > Catalog
2. Change Quantity to any number and save

Expected result

The product’s state is automatically changed to In Stock

Actual result

The product is still listed as Out of Stock despite the quantity change.

One must manually remember to also set In Stock which is a inconvenient step and not working as one would expect because the other way the state is changed.

I have noticed this as well.

Hi @peec , thanks for the suggestion. I've added internal ticket MAGETWO-55823 to our backlog.

Best,

Thank you for your submission.

We recently made some changes to the way we process GitHub submissions to more quickly identify and respond to core code issues.

Feature Requests and Improvements should now be submitted to the new Magento 2 Feature Requests and Improvements forum (see details here).

We are closing this GitHub ticket and have moved your request to the new forum.

I'm with 2.1.2 and have the same problem.

In 2.1.8 its not a problem. I think they've fixed on 2.1.0.
I compared vendor/magento/module-configurable-product/view/adminhtml/web/js/configurable-type-handler.js from 2.0.12 with 2.1.8 and realize they've made the required change there by commenting the entire _init method, and just added this.show(); there.
Take a look and apply the change properly by creating your own module to overwrite this; or update Magento.
Applying the above change re-enabled the Out of stock dropdown but will not update the field automatically (I think it shouldn't be automatically updated to in stock, only when is out of stock).
