System generated views just don’t seem to work reliably for me. Inline views are never generated (that might be me), but also details is 50/50. I have to remove and re-add stuff, or sometimes reloading works. I’m not doing anything crazy with the app, it’s basically blank other than what I’m trying to do.
In my experience and to the best of my recollection…
All tables automatically get system-generated detail and form views.
Tables that are the target of Ref (but not Enum or EnumList of Ref) columns get system-generated inline (table) views as well.
Slices that are the target of Ref (but not Enum or EnumList of Ref) columns get system-generated inline (table), detail, and form views.
All other views you have to generate yourself.
Form views are not auto-generated for and are not even allowed for explicitly read-only tables. Tables that are or can be rendered read-only by an Are updates allowed? expression are allowed form views.
