Magento2: Update items qty on cart or minicart doesn't work with several es_ locales

[barbanet]

I've created this issue also on M1 bug tracker because this problem cames from Zend_Locale and the locales xml definitions.

Using most of the es_ locales (es_ES and es_MX works fine) you aren't able to update cart quantities because the filter method on Zend_Filter_LocalizedToNormalized can't validate the number as number.

I understand that this problem is from Zend_Framework but I wasn't able to fix it yet.

When I try to update the quantity I get this message:

exception 'Zend_Locale_Exception' with message 'Unsupported token for numberformat (Pos 6):"#"

In my case I'm using es_AR as locale but also happens with another es_ locales too.

@barbanet does it happen in admin or in front-end? what are the steps to reproduce?

Hi @piotrekkaminski, I have the same issue when use es_AR locale. The steps to reproduce the problem are:

1- Install a clean magento 2.0.x
2- In admin panel, go to Stores > Configuration > General
3- set Country Argentina and locale Spanish(Argentina)
4- Create a simple product and a category.
5- Go to frontend and add to cart 4 items.
6- In frontend go to cart and try to modify item's qty.
7- When you submit the update, cart qty is reset to 1.

I have found the problem is in isNumber() on ../vendor/magento/zendframework1/library/Zend/Locale/Format.php

Hi @piotrekkaminski

The same problem reported by @barbanet for M1 is happening in M2

Here is the link with the explanation of the problem in the comments Issue #8461

The missing pattern es_419.xml or in each of your children is:

<decimalFormats numberSystem="latn"> <decimalFormatLength> <decimalFormat> <pattern>#,##0.###</pattern> </decimalFormat> </decimalFormatLength> </decimalFormats>

Any other missing definition in this file is a potential problem if it is not inherited from es.xml
