I had an app working under Rails 2.3.10 with activescaffold (NOT Volker's 
fork though.)
I wanted the config_list column picker to work, so I followed the directions 
to upgrade to Rails 3, then followed volker's directiosn to reinstall 
active_scaffold.
So, mostly working now, and finally I see the column picker interface. 
 Great!

But it seems wherever I used a virtual column before, like the "Action" 
column below (Model: :client_schedule has_many :events,  and :action is a 
column in client_schedule)

(app/controllers/events_controller.rb)
class EventsController < ApplicationController
 active_scaffold :events do |config|
    config.columns = [ ..., :action, ... ]
     config.columns[:action].includes = [:client_schedule]
 <snip>

(app/helpers/volumes_helper.rb)
module EventsHelper
 def event_action_column(record)
   record.client_schedule.action
 end
end

Now I get "undefined method `action' for #<Event:0x5fab4f0>"

It seems like my app/helpers/xxx files are being ignored.
Does Rails 3 handle helpers differently?
Does Volker's fork handle helpers differently?
