Created attachment 161715 [details] 500 error logs To recreate: 1. Edit the default framework, tag 100. 2. Edit subfield $e and add the authorized value RELTERMS. Save. 3. Find a bibliographic record and edit. 4. Find tag 100 and see that subfield $e has a drop down to select Relator Terms. 5. Edit the framework again for tag 100 $e. 6. In the box for Authorized Value, scroll to the top of the list and select the "blank" option. 7. Attempt to save. I would have expected that selecting the "blank" option in the authorized value list would remove the authorized value from that subfield. Database error message attached.
Possibly a database problem on my demo site. I will mark this as invalid for now and reopen if I can replicate on more than one site.
