Joomla 2.5 component : Invalid controller: name='', format='raw'

Joomla 2.5 component : Invalid controller: name='', format='raw'

im developing a custom joomla 2.5 component integrating jqGrid.
im setting up a controller task to handle (update mysql record) data sent
from jqGrid postData
var grid = jQuery(\"#list\");
grid.jqGrid({
onSelectRow: function(id){
$('#list').editRow(id, true);
},
url:
'/index.php?option=com_nutraidev&view=products&format=raw',
datatype: 'json',
mtype: 'GET',
colNames: [...],
rowNum: 25,
rowList: [5, 10, 20, 50],
height: 'auto',
pager: '#pager',
loadonce: true,
sortname: 'ID',
viewrecords: true,
direction:'RTL',
autowidth: true,
sortorder: \"desc\",
caption: 'abc',
width: '70%',
editurl:'/index.php?option=com_nutraidev&view=products&task=Products.save&token=".
JUtility::getToken() ."=1',
postData: {'code':\" \",....},
.....
this is the url which makes the request
/index.php?option=com_nutraidev&view=products&task=Products.save&token=".
JUtility::getToken() ."=1
im getting:
error 500
Invalid controller: name='products', format='raw'
tried it from the browser with the actual token - same result.
here is the important part of my code:
com_nutraidev - controllers - products.php
require_once JPATH_COMPONENT.'/controller.php';
class NutraidevControllerProducts extends NutraidevController
{
public function &getModel($name = 'Products', $prefix =
'NutraidevModel')
{
$model = parent::getModel($name, $prefix,
array('ignore_request' => true));
return $model;
}
public function save()
{
// Check for request forgeries.
JSession::checkToken() or jexit(JText::_('JINVALID_TOKEN'));
// Initialise variables.
$app = JFactory::getApplication();
$model = $this->getModel('Products', 'NutraidevModel');
$data = JRequest::get('get');
// Attempt to save the data.
$return = $model->updItem($data);
}
}
com_nutraidev - models - products.php
jimport('joomla.application.component.modellist');
class NutraidevModelProducts extends JModelList {
public function __construct($config = array()) {
parent::__construct($config);
}
public function updItem($data)
{
// set the variables from the passed data
$code = $data['code'];
$name = $data['name'];
// set the data into a query to update the record
$db = $this->getDbo();
$query = $db->getQuery(true);
$query->clear();
$query->update(' #__product ');
$query->set(' name = '.$db->Quote($name) );
$query->where(' code = ' . (int) $code );
$db->setQuery((string)$query);
if (!$db->query()) {
JError::raiseError(500, $db->getErrorMsg());
return false;
} else {
return true;
}
}
}
com_nutraidev - views - products - view.raw.php
jimport('joomla.application.component.view');
class NutraidevViewProducts extends JView
{
public function save($tpl = null)
{
echo "test";
jexit();
}
}
looking at other questions that had the similar issue i double checked my
administrator/components/nutraidev/nutraidev.xml
and made sure
<files folder="site">
<filename>controller.php</filename>
was there.
what could be the reason im getting this error ? i tried it also with
view.json.php and got the same result. thanks
