$product.attributes group_type in product list 1.7

[guil182]

Hi,

I'm  trying to display the $product.attributes in product list like in the product page.

So I try to adapt the product-variant.tpl to the product list.

So I change $groups by $product.attributes ( {foreach from=$product.attributes key=id_attribute_group item=group} )

 

BUT the var $group.group_type is undefined....:/

how to solve it ?

Regards
