Using ThinkingSphinx in ActiveScaffold, but the pagination links dont get created properly

controller.rb

class Admin::PostController < AdminController
  active_scaffold :post do |config|
    config.action_links.add 'sphinx_search', :label => 'Search'
    config.actions.exclude :search
    
    CRU_COLUMNS = [:name, :content]    
    config.list.columns = CRU_COLUMNS
    config.create.columns = CRU_COLUMNS 
    config.update.columns = CRU_COLUMNS
  end

  def sphinx_search
    if request.post?
      per_page = 20
      @results = Post.search(params[:search_term], :per_page => per_page, :page => params[:page])
      results = lambda {@results}
      @page = Paginator.new(@results.total_entries, per_page, &results).first
      @records = @page.items
      render :action => 'list'
      return
    end
    
    render :layout => false
  end

end
