To test: - Check out an item via web based self check - Click on 'renew' button or enter barcode again - Renewal form should display, giving you 'renew' or 'cancel' as options - Click on 'renew' -> Note that nothing happens. Wonder if this is something in my setup, but anyway there should be a helpful message instead of just a page reload. Couldn't find any error in the logs.
After some more testing OpacRenewalAllowed makes the difference. But the current behaviour makes no sense: Either we should not offer renewal functionality or it should work. :) I think it might be nice to have this controlled by a separate preference as the SCO is neither staff nor OPAC. If this ever worked, restoring former behaviour might be enough for a bug fix.
