If you go to a MARC bibliographic framework page like http://localhost:8081/cgi-bin/koha/admin/marctagstructure.pl?frameworkcode=&searchfield=100 and click "View subfields", you'll be taken to a list of subfields where the subfield code is linked like this: http://localhost:8081/cgi-bin/koha/admin/marc_subfields_structure.pl?op=add_form&tagfield=100&frameworkcode=#subafield If you click that, it'll take you to the "Edit subfield constraints" page but it'll have the 0 tab selected instead of the "a" subfield.
I am sure this used to work properly...
Created attachment 194044 [details] [review] Bug 41948: Fix links to subfield tabs in MARC bibliographic frameworks This patch fixes the URL fragment used to activate/select the appropriate tab in the tabs in the "Edit subfield constraints" tabs in the MARC bibliographic frameworks. Test plan: 0. Apply the patch 1. Go to /cgi-bin/koha/admin/marc_subfields_structure.pl?tagfield=100&frameworkcode= 2. Click on "a" next to "Personal name" 3. Note that you're taken to the "Edit subfield constraints" page and the "a" tab is active 4. Press the Back button in the browser and scroll to the far right and click the "Edit" button 5. Note that you're again taken to the "Edit subfield constraints" page and the "a" tab is active 6. Note without the patch, you'd be taken to the 0 tab each time
Authority types need the same fix as bib frameworks, according to the already signed off patch. *** This bug has been marked as a duplicate of bug 41838 ***
I've noticed this as well...
