Comment 8 for bug 1272566

I did poke at this for a while but wasn't able to fix the core issue. My bug fix works to allow adding UPC at order placement time... but I think that may have limited real life usefulness. Our acquisition staff member told me that the UPC usually is already in the record. So you still cannot select if it already exists, because it isn't possible to trigger setting the identifier if you cannot change from the one that gets shown initially and a second option.
