[TYPO3-shop] Product not found in basket

[Simon Justesen]

Hi,

I've done a tt_products-shop for a customer, who has two domains
the website is in 6 languages and the customer is able to select a language.

if people buy from domain 1 (a .dk domain) everything works, they're 
able to see the products in the basket, and complete the shopping no 
matter what language they select.

But if people are entering the site from domain 2 a (.com-domain) which 
point at domain 1, and select a language then the goods does not show up 
in the basket.
if people buy something and click the basket, the basket is empty.

Have you seen this behaviour before?

Best regards
Simon
