[TYPO3-shop] Problem with backPID

[Christian Lerrahn (Cerebrum)]

Hi,
I'm using a different page for the single view than for the list view
(I have to for TV template reasons). Now, this all works fine until
someone goes to an items single view and hits the back button there.
That will result in a backPID pointing to the single view and as soon
as I try to put anything in the basket, I'll see the single view with
an error message about the missing item uid.

How do I get tt_products to always post the basket updates to the list
view and ignore the backPID for anything but the back button?

Cheers,
Christian
