Get the value of a dropdown attribute of an associated product

Question

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.

Answer 1

Deactive the flat tables config

Or let it be active but set the attribute value "use in product listing" to yes (reindex data after that)
