Hi,
i tried to upgrade from rails 2.1.2 to rails 2.3.4 via:
-
envorinment.rb
RAILS_GEM_VERSION = ‘2.3.4’ unless defined? RAILS_GEM_VERSION
2) rake rails:upgrade
2.1) # envorinment.rb
config.action_controller.session_store = :mem_cache_store
2.2) # starting memcached locally
memcached -l 127.0.0.1 &
3) ruby script/server
4) calling localhost:3000 in the browser
(map.root :controller => ‘users’, :action => ‘login’)
5) i log in anf then i get the following error message:
ArgumentError in Module/toolsController#visibility
A copy of UserController has been removed from the module tree but is
still active!
RAILS_ROOT: …

This problem does not appear in production mode.
But in development mode.
I can solve the problem by setting “config.cache_classes = true” in
development.rb, but its no fun to work with that setting in development
mode.
Does anyone has ideas how to solve the problem?
Greeting,
Alexander
