I need update item by checkbox and click submit and send to actionUpdateItems
public function actionUpdateItems()
{
if(isset($_GET['pageSize']))
{
Yii::app()->user->setState('pageSize', (int)$_GET['pageSize']);
unset($_GET['pageSize']);
}
// allow POST request only
if(Yii::app()->request->isPostRequest)
{
$status = $_POST['ddlStatus'];
$chkPack = $_POST['chkPack'];
$currentday = date("Y-m-d"); //2012-02-08
$currenttime = date("H:i:s");
$orderid = $_POST['order-id'];
$select=!empty($_GET['op']) && $_GET['op']=='selected' ? 1 : 0;
if($status==='AP')
{
if($_POST['chkPack'])
{
Coin::model()->updateByPk($_POST['order-id'], array('PackD'=>$currentday, 'PackT'=>$currenttime,'SendD'=>$currentday, 'SendT'=>$currenttime, 'Doc_Flow'=>'S'));
}
else
{
Coin::model()->updateByPk($_POST['order-id'], array('PackD'=>$currentday, 'PackT'=>$currenttime, 'Doc_Flow'=>'P'));
}
}
elseif ($status==='P')
{
Coin::model()->updateByPk($_POST['order-id'], array('SendD'=>$currentday, 'SendT'=>$currenttime, 'Doc_Flow'=>'S'));
}
elseif ($status==='S')
{
Coin::model()->updateByPk($_POST['order-id'], array('Doc_Flow'=>'T'));
}
//Coin::model()->updateByPk($orderid, array('PackD'=>$currentday, 'PackT'=>$currenttime,'SendD'=>$currentday, 'SendT'=>$currenttime, 'Doc_Flow'=>'S'));
// if AJAX request, we should not redirect the browser
if(!isset($_GET['ajax']))
{
if(!$this->goBack())
$this->redirect(array('index'));
else
$this->goBack();
}
}
else
{
throw new CHttpException(400, 'Invalid request. Please do not repeat this request again.');
}
}
I test run on my localhost (windows7, php5.3, mssql2000). Everything is ok. But if I deploy to server(windows2000, php5.3, mssql2000). It show error “CoinController and its behaviors do not have a method or closure named “goBack”.”. After i add method goBack() in class. It is not show error but actionUpdateItems not work instead. 
Can i help me? Thank you for your advise.
