Session is cleared after each request

[lessless]

Hello! I faced an error using flash: undefined method `[]' for nil:NilClass and it looks like a bug. Further investigation showed that session is cleared after each request in the Lotus::Action::Callable#finish and thus it's no wonder that here is no "__flash" key in the session hash.

/Users/lessless/.gem/ruby/2.1.5/bundler/gems/controller-975feb8788de/lib/lotus/action/flash.rb:127:in `remove!'
/Users/lessless/.gem/ruby/2.1.5/bundler/gems/controller-975feb8788de/lib/lotus/action/flash.rb:65:in `clear'
/Users/lessless/.gem/ruby/2.1.5/bundler/gems/controller-975feb8788de/lib/lotus/action/session.rb:143:in `finish'
/Users/lessless/.gem/ruby/2.1.5/bundler/gems/controller-975feb8788de/lib/lotus/action/callable.rb:89:in `finish'

Can you post an example of the code you're using to cause this error?

it's something like this

module App
  class Application < Lotus::Application
    configure do
      layout :application
      load_paths << 'app'
      routes 'config/routes'
      default_format :json

      sessions :cookie, secret: 'mysecret'
      controller.prepare do
        expose :flash
      end
    end

    def self.root
      Pathname.new(File.expand_path(__dir__, '../..')).dirname.realpath
    end

  end
end


module App::Controllers::Submissions
  include App::Controller

  class Create
    include App::Action

    def call(params)
       flash[:success] = "OK!"
      redirect_to params.env["HTTP_REFERER"]
    end
  end
end
