https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=31154 --- Comment #13 from Emmi Takkinen <emmi.takkinen@koha-suomi.fi> --- Well this is confusing. I was able to repeat this bug again by adding a value in syspref "itemcallnumber" e.g. 084a. This triggers if-statement in Koha/Koha/UI/Form/Builder/Item.pm starting from line 151 which eventually leads Koha to crash on line 165. It seems that having a default value in default framework had nothing to with this at all since I too am unable to trigger this bug again with just default values. Here's an updated test plan: To test: 1. Confirm you have/set value to syspref "itemcallnumber" e.g. 084a 2. Find some item(s) to modify 3. Provide barcodes of those item(s) and check checkbox "Use default values" 4. Hit "Continue" => error 500 is raised -- You are receiving this mail because: You are watching all bug changes.
