    class Page_Controller extends ContentController {
       function RandomMetaKeywords()
       {
          if ($this->MetaKeywords)
             $HomePageValue = $this;
          else   
             $HomePageValue = DataObject::get_one('HomePage', '', '', '', '');
             
          $keywords = explode(', ',$HomePageValue->MetaKeywords);
