Developpment MVC Joomla 1.6 Invalid controller: name='data', format=''

[abeel162]

bonjour a tous,
je develope une composante joomla 1.6 dans mon fichier
admin.test.php:

...
// import joomla controller library
jimport('joomla.application.component.controller');

// Get an instance of the controller 
$controller = JController::getInstance('Test');

// Perform the Request task
$controller->execute(JRequest::getCmd('task'));

// Redirect if set by the controller
$controller->redirect();
...

dans la view:

/**
	 * Setting the toolbar
	 */
	protected function addToolBar()
	{
		$canDo = DataHelper::getActions();

		//Title Component
		JToolBarHelper::title(JText::_('COM_TEST_ADMINISTRATION'), 'test');

		if ($canDo->get('core.create'))
		{
			JToolBarHelper::addNew('data.install', 'JTOOLBAR_INSTALL');
		}
	}

dans le package controllers j'ai data.php:

// No direct access to this file
defined('_JEXEC') or die('Restricted access');

// import Joomla controller library
jimport( 'joomla.application.component.controller');

/**
 * Data Controller
 */
class TestControllerData extends JController
{
public function install()
	{
echo 'erewrew';
die();
}
}

lorsque je click sur le boutton install j'ai l'erreur suivant:

 Invalid controller: name='data', format=''
