A copy of ApplicationController has been removed from the module tree but is still active!

Was having this issue with the /admin/config page after I locked the page behind authlogic.

Fixed by making that controller unloadable

Seems to be a common issue:

Not sure if that's an issue with your code or theirs - but that's how I fixed it for me.

Hey,

What version of Rails?

Did you use Behavior.before_filters to lock the the page?

It was using Rails 2.3.5 on OSX 10.6.2 - ruby 1.8.7.

Basically I just added a before filter to the page, and that's when it went all freaky-deaky on the second page load - here's the code:

I just added the require_user before filter and until I added unloadable, every time you would reload the page (a second time - the first always worked) it freaked out.

Hi darron,

Try creating an initializer in config/initializers/behavior.rb with this:

Behavior::Config.before_filters = [:require_user]

You shouldn't need to edit any code in the plugin itself.

I added this to the initializer:

Behavior::Settings.before_filters = [:require_user]

Restarted the app and it still happens until I add unloadable.

It will render the page once, and on the second page load it still craps out. (until I add unloadable)

It may be a one off issue, and I've got a workaround, so it's honestly no big deal.

I ran into the same issue trying to use behavior with authlogic.

Per the article linked above (http://strd6.com/?p=250), unloadable is now deprecated, so there's another simple solution. Put the following into your environment.rb file:

config.reload_plugins = true if RAILS_ENV == 'development'

This worked for me, but it would be great if there was some fix (or at least documentation) in the behavior code. Lots of people using authlogic...
