We were working in a record view, while editing a relationship (nothing smart about all of this).
I think I was trying to migrate code I wrote before the dropdown filter was an option. This post certainly seems to indicate so:
Relationship dropdown edit widget filter - how to filter dataset based on current entity - Help me! - Forest Admin Developers Community
Who knew using undocumented hacks could backfire in any way?
I’m actually noticing that this suggestion was implemented:
Noice. Thanks folks. We even have autocomplete.
I believe I marked my previous message as the solution, do I need to do anything else on the post?
