It won't always be desirable to preserve the original query string because
the Ajax callback is not really requesting the original parent page but
instead merely using the original action to access the autocomplete
functionality. However, it would probably be a good idea to add an option
to the autocomplete widget allowing the query string to be preserved, so
you should submit a github issue about this (link back to this thread).
For now, though, there are three possible workarounds:
1. Because the URL args are preserved, you can put the step in a URL arg
instead of a "step" variable in the query string.
2. You can store the step in the session rather than in the URL (not
good for bookmarking).
3. You can manipulate the widget after it has been instantiated (haven't
tried it, but I think it should work):
city_widget = SQLFORM.widgets.autocomplete(request, db.city.name,
id_field=db.city.id)
city_widget.url = URL(args=request.args, vars=request.get_vars)
db.person.city.widget = city_widget
Also, note that there is an error in your code -- you are assigning the
widget to db.person.city rather than to db.person.city.widget.
