I'm trying to display the (non empty) attribute values of all associated products in a grouped product.
My main issue are the dropdown attributes
I can display the manufacturer value but not the color one. Any other custom attribute is not visible either.
I have tried to solve it using this solution: https://stackoverflow.com/questions/8754579/is-it-possible-to-show-custom-attributes-of-associated-products-under-a-grouped
I have also tried loading a specific associated product by Sku without success.
