custom field child product

[philipperunza]

Bonjour
i use virtuemart 2 et joomla 2.5

In order to manage my product i use two custom field

a Generic Child Variant for the shape and cart variant for the color

the problem is that this two custom field are manage  in the parent product


it's not a problem for the   Generic Child Variant  because it allow to create the product child and must be manage in the parent product but if i try to attribute a list of color for each child product with the  cart variant it doesn't work


if i use the option overload parent product , it give a wrong result

i don't know how to proceed


best regard
philippe
