https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=37226 Bug ID: 37226 Summary: Authority hierarchy tree broken when a child (narrower) term appears under more than one parent (greater) term Change sponsored?: --- Product: Koha Version: Main Hardware: All OS: All Status: NEW Severity: normal Priority: P5 - low Component: MARC Authority data support Assignee: koha-bugs@lists.koha-community.org Reporter: a.roussos@dataly.gr QA Contact: testopia@bugs.koha-community.org Created attachment 168314 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=168314&action=edit short screen recording that shows the bug in action With AuthDisplayHierarchy enabled and the following MARC21 authority data: 001 1 151 $a Europe 551 $a Athens $w h $9 3 942 $a GEOGR_NAME 001 2 151 $a Greece 551 $a Athens $w h $9 3 942 $a GEOGR_NAME 001 3 151 $a Athens 551 $a Europe $w g $9 1 551 $a Greece $w g $9 2 942 $a GEOGR_NAME In the authority details page for 'Athens' (authid=3), clicking on the expand/collapse arrows next to the top-level terms in the hierarchy tree ('Europe' and 'Greece') will not work properly, i.e. *only one* broader term will show 'Athens' as its narrower term at any given time. I attach a small screen recording that shows this in action. -- You are receiving this mail because: You are the assignee for the bug. You are watching all bug changes.
