Cannot modify header information

Good Day!

I'm trying to saving the contents of my form, I'm using CJuiDialog and CActiveForm at the same time. There's is no problem in the form, the problem occurs when hitting the save button.

Here is the description of error returned by PHP:

Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\ADS\protected\controllers\CreditorDebtorController.php:73)

here is the stack trace:

     public function redirect($url,$terminate=true,$statusCode=302)
654     {
655         if(strpos($url,'/')===0)
656             $url=$this->getHostInfo().$url;
[color="#FF0000"]657         header('Location: '.$url, true, $statusCode);[/color]
658         if($terminate)
659             Yii::app()->end();
660     }

Stack Trace #2

098                                 exit;
099                             }
100                             else
101                             //print_r($_POST['CreditorDebtor']);    
[color="#FF0000"]102                             $this->redirect(array('view','creditorId'=>$model->creditorId));[/color]
103                         }
104                    
105                         //$this->renderPartial('_form',array('model'=>$model));
106                     }
