Hi, found a problem in opac earlier today. To recreate do a search in opac and then change the sorting of the result set you get a 500 error. The perl tests building the ZOOM module also fail on the sorting tests. I reported it on the indexdata zebra list and the indexdata guys think its a bug that crept in with yaz 5.0.13. Hopefully its easily fixable Colin -- Colin Campbell Chief Software Engineer, PTFS Europe Limited Content Management and Library Solutions +44 (0) 800 756 6803 (phone) +44 (0) 7759 633626 (mobile) colin.campbell@ptfs-europe.com skype: colin_campbell2 http://www.ptfs-europe.com
