Taxonomy term argument validator should not validate terms defined in other languages
>>> [!note] Migrated issue
<!-- Drupal.org comment -->
<!-- Migrated from issue #832100. -->
Reported by: [stewart.adam](https://www.drupal.org/user/586244)
>>>
<p>The "Term Name" argument validator which converts a term name into its corresponding term ID does not filter for terms by the current language. If two or more languages have the same term name, then results are returned for the wrong language when using term name is used as an argument (and if i18n content filtering is added to the view, then no results return at all).</p>
<p>I'll explain how I ran into the problem: I am creating an Ubercart store where certain items can be purchased from an artist's special collection. I've created a custom View that displays a grid of the products available based on the taxonomy term supplied as an argument to the View. The View has one argument (Taxonomy: Term ID) and the term name is converted to its corresponding term ID using the "Term Name/Synonym converted to Term ID" validator.</p>
<p>The path <em>/en/products/category_name</em> works fine because the term category_name is different in each language.<br>
The path <em>/en/products/artists_name</em> actually returns the same thing as <em>/fr/products/artists_name</em>. If i18n content filtering is on, then <em>/fr/products/artists_name</em> returns English nodes, so no products appears in the View.</p>
<p>I have found a fix for this by overriding the stock validator plugin, but I don't know if there's a better way to approach this problem.</p>
