i'm using stwe/datatablesbundle symfony 2 (http://github.com/stwe/datatablesbundle) (stable version v0.6.1) , getting following error:

catchable fatal error: argument 1 passed sg\datatablesbundle\datatable\view\abstractdatatableview::__construct() must instance of symfony\bundle\twigbundle\twigengine, none given, called in g:\server\www\bongoapp\app\cache\dev\appdevdebugprojectcontainer.php on line 418 , defined

i have tried following answer here, not working me. doing wrong? code below , in advance:

generated datatable class: 

namespace bbd\bongoappbundle\datatables;  use sg\datatablesbundle\datatable\view\abstractdatatableview;  /**  * class artistdatatable  *  * @package bbd\bongoappbundle\datatables  */  class artistdatatable extends abstractdatatableview { /**  * {@inheritdoc}  */ public function builddatatableview() {     $this->getfeatures()                     ->setserverside(true)                     ->setprocessing(true);              $this->getajax()->seturl($this->getrouter()->generate('artist_results'));      $this->setstyle(self::bootstrap_3_style);       $this->getcolumnbuilder()             ->add('id', 'column', array('title' => 'id',))             ->add('name', 'column', array('title' => 'name',))             ->add('bangla_name', 'column', array('title' => 'bangla_name',))             ->add('birth_place', 'column', array('title' => 'birth_place',))             ->add('priority', 'column', array('title' => 'priority',))             ->add('bday', 'column', array('title' => 'bday',))             ->add('bmonth', 'column', array('title' => 'bmonth',))             ->add('byear', 'column', array('title' => 'byear',))             ->add('sex', 'column', array('title' => 'sex',))             ->add('dod_day', 'column', array('title' => 'dod_day',))             ->add('dod_month', 'column', array('title' => 'dod_month',))             ->add('dod_year', 'column', array('title' => 'dod_year',))             ->add('bio_english', 'column', array('title' => 'bio_english',))             ->add('bio_bangla', 'column', array('title' => 'bio_bangla',))             ->add('real_name', 'column', array('title' => 'real_name',))             ->add('debut', 'column', array('title' => 'debut',))             ->add('graphics.id', 'column', array('title' => 'graphics id',))             ->add('graphics.thumbnail', 'column', array('title' => 'graphics thumbnail',))             ->add('graphics.poster', 'column', array('title' => 'graphics poster',))             ->add('graphics.feature', 'column', array('title' => 'graphics feature',))             ->add('graphics.gallery', 'column', array('title' => 'graphics gallery',))             ; }  /**  * {@inheritdoc}  */ public function getentity() {     return 'bbd\bongoappbundle\entity\artist'; }  /**  * {@inheritdoc}  */ public function getname() {     return 'artist_datatable'; } }

controller

public function indexaction() {     $postdatatable = $this->get("bbd_datatables.artist");      return array(         "datatable" => $postdatatable,     ); }  public function indexresultsaction() {     /**      * @var \sg\datatablesbundle\datatable\data\datatabledata $datatable      */     $datatable = $this->get("bbd_datatables.datatable")->getdatatable($this->get("bbd_datatables.artist"));        return $datatable->getresponse(); }

services.yml

  bbd_datatables.artist:      class: bbd\bongoappbundle\datatables\artistdatatable      tags:         - { name: bbd.datatable.view }

and index.html.twig

{% block content_content %} {{ datatable_render_html(datatable) }} {% endblock %} {% block javascripts %} {{ parent() }} {{ datatable_render_js(datatable) }} {% endblock %}

it seems you've used wrong tag.

bbd_datatables.artist:    class: bbd\bongoappbundle\datatables\artistdatatable    tags:       - { name: sg.datatable.view }
