The patch only partly fixes the problem. Now the backPID is correct but
the parameter tx_ttproducts_pi1[product] does not get deleted from the
URL, so that the list view on return will display a single item, too. :(

I'm sorry for having brought this up on the mailing list instead of
reporting a bug on the bug tracker. I wasn't sure at first if this was
a bug or just a configuration problem. Please let me know if you want
me to write a bug report instead.

Cheers,
Christian
