Hi,
it would be nice if using a field type choice field with behavior autocomplete would not only set configured target fields in the columns of general tab in advanced configuration. When the choice field gets deleted and is empty the target field values remain instead of getting deleted too. To get them deletion one hase to create a form rule. This wouldn't be necessary any more if there would be this automatically or as an option in general tab kind of "Delete values of target fields if choice value is empty".
Kind Regards
Sébastien
