Where is assigned $product.grouped_features ?

[HeineFR]

Hi,

I've got a big problem.

I'm making my AMP pages and i simply want to add the features on it.

I found in "\themes\*****\templates\catalog\_partials\product-details.tpl" : 

{if isset($product.grouped_features) && $product.grouped_features}

But in my tpl file this var seem to be not assigned, i have to assign it in my php file.

Then, i grep on my server the word 'grouped_features' to find where and how it's assigned but it only return me my tpl files (the new one where i try and product-details.tpl) and smarty compiled files.

I'm not able to find where this var is assigned can i have some help please?

 

PS 1.7.5.1

The "grouped_features" variable is generated dynamically in the getGroupedFeatures() method of the ProductLazyArray class:
