[TYPO3-shop] false price when insert in basket

[Niels Tiedt]

Hi List
I have another problem with the 2.7.0
At the moment i cannot update to the newest 2.7.0 version
My problem is the following one
I have an product with 2 variants.
All 3 content elements are insert and configured.
Now i go shopping in the fe.
In the single view i switch to the second variant.
The price is changed correctly e.g. to 100 eur
But when i buy the product the mini-basket and the basket show me the 
wrong price.
It shows the price of the product not the variant.

For test puposes i have changed price1 to 0 and price2 to e.g. 10 in the 
product.
Now in the fe it show at the start 0 eur.(and this is the reason why i 
cannot use it)
I switched to the 2. variant an the price changed correct and when i 
insert it to the basket
the right price is shown e.g. 100eur

have anyone an idea?
please help
thx niels
