http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=15246 --- Comment #1 from Laura <lauraerinmann@gmail.com> --- I was able to get past this by changing my Home > Administration > System Preferences > Patrons. I noticed that the "BorrowerUnwantedField was set to "title|dateofbirth|branchcode" This was causing the field not to render (even as a hidden field). By removing branchcode from BorrowerUnwantedField, the branchcode field now renders, and chooses as it's only option our library branch code (our koha instance only has one libary). As for solutions, instead of getting the database error and having to chase through mysql logs, I would have ideally been met with a more understandable "Branch code is required" or better yet, the branch code, being a required field, should be rendered as a hidden input or computed server side. -- You are receiving this mail because: You are watching all bug changes.
