more problems with functional tests

[thoughtafter]

I've been working on trying to fix tests after migrating from
authlogic to devise for some time now. I seem to have reached an
impasse with a functional test. This problem seems to be specific to
this particular controller and only for put / post requests. Whenever
a put or post request is performed the controller always redirects to
the sign in page, despite the fact the user seems to be logged in.
Also, though the tests fail the code seems to work fine. This is
using devise 1.0.10, warden 1.0.3, rails 2.3.11, tested with ruby
1.8.7 and ruby 1.9.2. I've extracted a portion of the test:

context "when signed in" do
setup do
@user = Factory.create(:user)
@event = Factory.create(:event_listing)
sign_in @user
end

context "on GET to edit" do
setup do
# :edit is protected by :authenticate_user!
get :edit, :city=>@event.city.url, :id=>@event.id
end

should respond_with :success
should render_template 'edit'
end

context "on PUT to update with no changes" do
setup do
# :update is protected by :authenticate_user!
put :update, :city=>@event.city.url, :id=>@event.id
end

should "debug" do
puts "\nUser active?: #{@user.active?}"
puts "Flash: #{flash.inspect}"
end

should respond_with :redirect
should redirect_to('edit url')
{{:action=>:edit, :id=>@event.id}}
end

end

Here is the run:

$ ruby -I test/ test/functional/events_controller_test2.rb

Flash: {}

5 tests, 7 assertions, 1 failures, 0 errors

It should also be noted that if I change the authenticate_user! line
to:

before_filter :authenticate_user!, :except => [:update]

The tests pass correctly, though obviously I do not wish to have this
action unprotected. Also I have shown that there are no flash
messages and the user.active? is true. So what are the next steps to
resolve this?
