[Koha-bugs] [Bug 41060] Add a value_builder to check if ISSN is valid

https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=41060 Marcel de Rooy <m.de.rooy@rijksmuseum.nl> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|Signed Off |Failed QA --- Comment #3 from Marcel de Rooy <m.de.rooy@rijksmuseum.nl> --- Some observations: If I leave 022 empty, there is a warn about invalid ISSN. Thats weird. Please fix. If I enter a valid ISSN like 1234-5679, it is ok. If I enter 1234-5679A, it is ok too and that is confusing. If I enter 1234-5679X, it is wrong. Coming from Business::ISSN. So out of scope ? -- You are receiving this mail because: You are watching all bug changes.
