WillPaginateCustomUrlFix.rb

class WillPaginate::ViewHelpers::LinkRenderer
  
  def url(page)
    @base_url_params ||= begin
      url_params = base_url_params
      merge_optional_params(url_params)
      url_params
    end
    
    url_params = @base_url_params.dup
    add_current_page_param(url_params, page)
    
    @options[:url] ? merge_parameters_with_string_url(@options[:url], url_params) : @template.url_for(url_params)
  end
  
  def merge_parameters_with_string_url(url, url_params)
    url_params = url_params.except(:escape, :controller, :action)

    string_attributes = url_params.collect do |key, val|
      "#{key}=#{CGI::escapeHTML(val.to_s)}"
    end
    
    url + "?#{string_attributes.join("&")}"
