Unless I'm missing something, it looks like this will have the
same problem I've been battling. After the loop executes and the zone is
updated, the purchaseRequest, in this case, will always be the last
purchaseRequest encountered by the loop. Please correct me if I am
incorrect.
At this time, I've decided to resort to writing some javascript, instead of
using a zone update, to change the choices in my 2nd select when the value
of the 1st select changes.
