https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=18499 --- Comment #2 from Nick Clemens <nick@bywatersolutions.com> --- To clarify, in a system with mixed classification sources the callnumber browser uses the DefaultClassificationSource defined in the sysprefs for all browsing. This is problematic in some situations, for instance: '2017 SCHM' is a generic callnumber, if you set the Default to 'LOC' you get back a blank string To recreate: 1 - Set DefaultClassificationSource to LOC 2 - perl -e "use C4::ClassSource; print GetClassSort( undef, undef, '2017 SCHM' );" 3 - You get no feedback 4 - Set DefaultClass.. to Dewey 5 - repeat #2 6 - You get a populated string -- You are receiving this mail because: You are watching all bug changes.
