To test: 1) Go to /cgi-bin/koha/serials/subscription-numberpatterns.pl and try creating a new pattern, notice that only Name and Description are mandatory after applying this patch 2) Make sure editing existing numbering patterns still works -- You are receiving this mail because: You are watching all bug changes.
