Hmmm... I'm not using Ajax, but there is a JS, which can -- in some cases --
reload the page ()... let me see...
... alas, nope. It does not seem to be the culprit.
Well, I sort of solved it by checking whether the market ID is non-null and
whether there's a market for the ID etc, silently returning null if not -- so
hopefully, it won't harm much.
Thanks a lot!
