Formlib and multiple forms

Hi,

I'm not sure if I'm going about this the right way but I'm struggling
with using formlib to generate a group of forms / set of repeating
elements in what is effectively a grid. I think that either I need to
use a collection or a set of forms with different prefixes but I'm
still struggling a bit with this.

I have a concert object type that takes place in several cities so the
repeating element would be the city with the additional information
such as date, address and price. Effectively I have two schemas and
while I could, I suppose use two different objects (Concert &
Location), it is important that for the application that the Location
information for all venues can be edited at once: effectively a list
of dictionaries with each key corresponding to a field. Is it possible
to extend a schema like this? Alternatively, and I think this probably
makes more sense: how to do I get the form to be extended repeatedly
with the same interface but a different prefix?

Guidance much appreciated!

Ah, it looks like I've got this working:

def setUpWidgets(self, ignore_request=False):
self.widgets = []
for city in ["Paris", "New York"]:
self.adapters = {}
self.widgets += setUpWidgets(
self.form_fields, city, self.context, self.request,
form=self, adapters=self.adapters,
ignore_request=ignore_request)

Is this okay? Or is it a bad thing (TM)?

I guess it's a bad thing as the form buttons retain the prefix "form"
even if the widgets get "Paris" and "New York" prefixes. Oh well, back
to the drawing board.
