+ # Problem: set_pricegroup resets the sellprice of old invoices to the price
+ # currently defined in the pricegroup, which is a problem if the price has
+ # changed, as the old invoice gets the new price
+ # set_pricegroup must never be called, when an old invoice is initially loaded

+ # set_pricegroup($_) for 1 .. $form->{rowcount};
