Hi all, I got this error when I tried to catalog new books into koha. Koha error The following fatal error has occurred: |Can't call method "fields" on an undefined value at /usr/share/koha/lib/C4/Biblio.pm line 1642. | Apache Server version: Apache/2.2.3 Server built: Mar 22 2008 09:29:10 Koha 3.00.00.107 Koha DB 3.0000107 MySQL mysql Ver 14.12 Distrib 5.0.32, for pc-linux-gnu (i486) using readline 5.2 OS Linux frodo 2.6.18-4-686 #1 SMP Wed May 9 23:03:12 UTC 2007 i686 GNU/Linux Perl 5.008008 I had a look at the log and I found this [Thu Dec 11 11:58:01 2008] [error] [client 10.100.10.149] [Thu Dec 11 11:58:01 2008] additem.pl: Can't call method "fields" on an undefined value at /usr/share/koha/lib/C4/Biblio.pm line 1642., referer: http://koha/cgi-bin/koha/cataloguing/addbiblio.pl?biblionumber=0&z3950=1&breedingid=3009 And I found that this would only happen for some books, not all books. Anyone can help me? Thanks. Ming214 -- View this message in context: http://www.nabble.com/error-occurs-when-adding-new-biblio-tp20947736p2094773...
