_join form. There were no errors, but not all of the resource associations were present. Looks like here https://github.com/ash-project/ash_phoenix/blob/main/lib/ash_phoenix/form/auto.ex#L469 we use Enum.find, so we are only getting the first occurence of the association. I tried editing it to Enum.filterand changing the type from :single to :list. This made the associations properly appear in the form, but submitting it failed. :list and handle the length = 1 case for single?
