Just stumbled upon this in 17.11 and 17.05 when this syspref is on. Upon saving a patron without putting any cardnumber, since autoMemberNum and checkdigit is both turned on, I am getting the following error: DBIx::Class::Storage::DBI::_dbh_execute(): Duplicate entry "V18" for key 'cardnumber' at /usr/share/koha/lib/Koha/Object.pm line 121 With this being said, all the more this system preference setting should go. I just put in this comment since it's related to this bug no. Should this also be backported to 17.11 and 17.05? -- You are receiving this mail because: You are watching all bug changes.
