To see the behavior see this diff:
http://roadsignmath.com/w/index.php?title=Illinois_Cancellation&diff=prev&oldid=6700
That diff is the result of this autoedit call:
c = wiki.call({'action': 'sfautoedit', 'form': 'Sign', 'target': title, 'Sign[State]': result.rows[0]['state'], 'Sign[City]': result.rows[0]['city'], 'Sign[County]': result.rows[0]['county'], 'Sign[Country]': result.rows[0]['country'] })
Note that "Coordinates" is not one of the fields being edited. When the edit occurs Semantic Forms moves the fields around in the Template as it usually does, but the Coordinates field contents are lost in the process.
I've got Semantic Forms 2.5.1 and SMW 1.9 alpha.
