php - Joomla: error while saving form in custom view -

i have created custom component form update prices of 4 product displayed on frontend.

my main controller code here:

public function display($cachable = false, $urlparams = false) {      require_once jpath_component.'/helpers/calculator.php';      $view       = jfactory::getapplication()->input->getcmd('view', 'pricetable');     $layout     = jfactory::getapplication()->input->getcmd('layout', 'edit');      jfactory::getapplication()->input->set( 'layout', $layout );     jfactory::getapplication()->input->set('view', $view);     jfactory::getapplication()->input->set('id', 1);      parent::display($cachable, $urlparams);     return $this; } 

id set 1 loads first row database.

code pricetable container is:

function __construct() {     $this->view_list = 'pricetable';     parent::__construct(); } 

now in admin backend form loaded desired first row of data. when try save form redirected administrator/index.php?option=com_calculator&view=pricetable , error is:

error: not permitted use link directly access page (#1).

my form action is:

<?php echo jroute::_('index.php?option=com_calculator&task=pricetable.edit&id='.(int) $this->item->id); ?> 

please suggest doing wrong. third day i'm scratching head. :(

you can updating actions (or calling them) inside code whenever is. new instance or update new - add 1 more if in code , hidden input on form. example:

<input type="hidden" name="task" value="update" />
