Can't order products with multiple variants from mod_iso_productvariantlist

The list module for product variants allows adding products to the cart directly without visiting the reader page.
Technically, it does this by placing hidden form fields into the markup which contain all relevant product identifiers.

I've found out that one of this fields is not generated correctly by the template iso_list_variants.html5.

<div class="formbody">
    <input type="hidden" name="FORM_SUBMIT" value="fmd3_product_101">
    <input type="hidden" name="REQUEST_TOKEN" value="87d557424dc75258cf7c7acbff0c8103">
    <input type="hidden" name="AJAX_PRODUCT" value="101">
    <input type="hidden" name="AJAX_MODULE" value="3">
    <input type="hidden" name="liter" value="11 Liter">
[…]
</div>

The regular form on the reader page has the following options for the variant attribute:

<select name="liter" id="ctrl_liter_fmd4_product_101" class="select mandatory" required="">
    <option value="liter_11">11 Liter</option>
    <option value="liter_27" selected="">27 Liter</option>
    <option value="liter_45">45 Liter</option>
</select>

As you can see, the value in the latter case is „liter_11“, whereas it it „11 Liter“ in the list template. The wrong value confuses the module and one cannot place such products into the cart directly. It is required to first navigate to the reader page and then order the product.

In my eyes, the line of code should not output the display value of the variant attribute, but rather the real value.

Superb!
