php - Form made in Yii returns error, Property is not defined -

i have controller ecommercecontroller.php , looks this:

public function actionlegalisation()     {         $model = new product();  $this->render('legalisation', array('model'=>$model, 'documents'=>$documents, 'countriesissued'=>$countriesissued, 'countries'=>$countries, 'flag'=>$flag));     } 

and in legalisation view have:

<?php $form=$this->beginwidget('cactiveform', array(     'id'=>'legalisationform',     'action' => $this->createurl($this->id."/".$this->action->id),     'enableajaxvalidation'=>true,     'clientoptions' => array(   'validateonsubmit'=>true,   'validateonchange'=>true,   'validateontype'=>false,      ), )); ?>     <table>         <tr>             <td>                 <?php echo $form->dropdownlist($model, 'countriesissued', $select = array($_post['countriesissued'])); ?>             </td>         </tr>     </table>

<?php echo chtml::dropdownlist($form, 'countriesissued', $select = array($_post['countriesissued']),                   chtml::listdata($countriesissued, 'code', 'name')); ?>
