php - joomla 3.x tags in custom component fails -


running joomla 3.3.0-dev

i'm following info posted here adding tag support third-party component.

i've added content type #__content_types table , modified table file this:

class mycomponenttableelement extends jtable {     public $tagshelper = null; // failed when protected , public      public function __construct(&$_db)     {         parent::__construct('#__mycomponent', 'id', $_db);         // add joomla tags         jobservermapper::addobserverclasstoclass('jtableobservertags', 'mycomponenttableelement', array('typealias' => 'com_mycomponent.element'));         //$this->_observers = new jobserverupdater($this); jobservermapper::attachallobservers($this); // failed or without line       }

i added tag field in edit template, , worked fine-- when save object following error:

save failed following error: unknown column 'tagshelper' in 'field list'

what missing? there's no other steps (besides front-end steps!) mentioned. seems need modify model info not applicable.

thanks

"this page needs copy editing" , it's true!

i follow initial steps described in page

  • register 'content type' extension view(s)
  • add 'observer methods' extension table class(es)
  • add 'tag fields' extension edit forms

but make field tag works on custom extensions need explicit set form field value in view file of backend:

$tagshelper = new jhelpertags;  $this->form= $this->get('form');  $this->form->setvalue('tags', null, $tagshelper->gettagids( $this->item->id, 'com_custom.viewname') );

in way on edit page seems work correctly.. surely exist better , more clean method, until doc page not updated, can someone!
