I get this error with latest out of trunk:

Authlogic::Session::Activation::NotActivatedError in Catalog#index

Showing vendor/plugins/blacklight/app/views/catalog/_bookmark_control.html.erb where line #1 raised:

You must activate the Authlogic::Session::Base.controller with a controller object before creating objects

Extracted source (around line #1):

1: <% if current_user and current_user.document_is_bookmarked? document[:id] %>
2: <span>This item is in your <%= link_to 'bookmarks', bookmarks_path %></span>

=====================================

I've monkey patched my copy to comment out the following in the plugin's application_controller.rb:
 def current_user_session
      return @current_user_session if defined?(@current_user_session)
      #@current_user_session = UserSession.find
    end

    def current_user
      return @current_user if defined?(@current_user)
      #@current_user = current_user_session && current_user_session.user
    end

When application_controller.rb from the plugin is copied to the rails application level leaving @current_user uncommented works. For some reason it only fails for the version inside the plugin.

I should also say that it works uncommented on one machine but not on another. The machine where it is not working is running Ruby Enterprise Edition.
