Answer 1

You're not returning the Customer model in your loadCusModel method in your controller, when there is a row found with that id:

if($customer_form===null) {
       throw new CHttpException(404,'The requested page does not exist.');
       return $customer_form;
}

You're only returning it if $customer_form is null. So put the return outside the if-statement and it will work:

if($customer_form===null) {
       throw new CHttpException(404,'The requested page does not exist.');
} 
return $customer_form;
