Michal, thanks for following up.
I'll try your suggested code from your other response upthread and see if
it solves the problem as well as the form.__init__.
And do more digging about how Python does things. I am a self-taught
programmer who focuses on community economic development and I usua

You were calling the method in the class definition. The class is
"defined" when the module is imported. That's why things where
"cached". Module is imported only once.
The init method on the other hand is called every time an instance of
the class is created. I believe that method will be called i

Yes, that's what I did. It worked for the form field.

Hello,
This is trivial mistake. Use form.__init__ if you would like to change it
dynamically

I'd guess you're doing a query for the form field's choices at the module
level which will be executed once and cached for as long as the server
