Show view does not accept actions parameter in sfAdminThemejRollerPlugin

Change getShowActions() method in plugins / sfAdminThemejRollerPlugin / data / generator / sfDoctrineModule / joller / parts / showConfiguration.php to this:

public function getShowActions()
  {
    return <?php echo isset($this->config['show']['actions']) ? $this->asPhp($this->config['show']['actions']) : "array(  '_list' => NULL,  '_edit' => NULL, '_delete' => NULL)" ?>;
    <?php unset($this->config['show']['actions']) ?>
  }
