Clicking in quantity box changes default 1 to Undefined #3932
On any product category list, when clicking in the quantity box the existing 1 text immediately changes to "undefined". Then if you type in any number and click Add to Cart the popup shows no product and it is not added to the cart. The - and + buttons work to change quantity and product is added to cart. This only happens on product category list, not on product details page.
Virtuemart forum's only mention of "undefined quantity" referred to an update to components/com_virtuemart/sublayouts/addtocartbar.php since Virtuemart 3.0.12. The undefined issue in that case was caused by a template/html/ override of that file that wasn't updated. I don't believe that's the reason for my issue. I can't locate any VMuikit override for that file.
Clicking in quantity box changes default 1 to Undefined #3935
I discovered the cause of this error. It was an HTML override of plugin/system/vmuikit_override/html_override/com_virtuemart/themes/grids/products/list.php that I created from an older version of VMuikit. I didn't update the code when updating to VMuikit 3.1.6.
I have to remember the display view tmpl files of VMuikit are modified with each new version, so the HTML overrides must be updated each time, too. Sort of defeats the benefits of overrides. I may as well just hack the core VMuikit files. It's the same amount of work to keep overrides.
