attribute_check for controllers in subfolders

[Houdini]

I have controller in
app
controllers
client_interface
client_reader

well, Controller defenition is

class ClientInterface::ClientReaderController < ApplicationController
before_filter :load_client
filter_access_to :all, :attribute_check => true
layout 'client'
def show
date_for_date_chooser
end

protected
def load_client
@client = Client.find params[:id], :include => :wallets
end

end

I get error when add :attribute_check => true, error: uninitialized
constant ClientReader

I am talking with myself
Well problem was not in subfolders, but declarative authorization was
incorrect detect the context, so I show it by hands, smth like this:

class ClientInterface::ClientReaderController < ApplicationController
before_filter :load_client

filter_access_to :all, :attribute_check => true, :load_method =>
lambda{@client}

layout 'client'
def show
date_for_date_chooser
end

protected
def load_client

@client = begin

Client.find params[:id], :include => :wallets

rescue ActiveRecord::RecordNotFound
nil
end
end

end
