How to display view product_display > product_reference > fits_with (product_display reference)

Using commerce module I have setup an eshop with clothes related to each other using fits_with reference

here my content type
product_display
title
product: commerce product reference
fits_with: product_display reference

I want to be able to format the product_display reference using a view (using EVA)

I created a view that outputs product_display's
with EVA settings
Entity type: node
Bundle type: product display
Argument: token [node:field-product:field_fitswith]

Relationships
Content: Product
(Product) Commerce Product: Fits with

CONTEXTUAL FILTERS
Display contents of "No results found"
Specify validation criteria
Validator Content : product_display
Filter Value: nid's

what am I missing ?

NOTE:
I have succesfully setup EVA with other less complicated setups
I have read all the examples in #1111222: How to use it? but I still cann't get it to work

I would appreciate any help
