AutoForm: No good examples of updates available

Howdy all, looking for a good example of AutoForm update.

The insert goes just swell, but it’s not exactly crystal clear as to how one would update autoform with existing data and save over it. There some sort of helper system needed, I can’t figure it out…

This guys close I think?

Update: Oh actually yeah this guy got it. I just got it working too. Weird. Cool.
