[TYPO3-mvc] Scheduler & Extbase error of dispatcher controller

[Lim Chivy]

Hello,

I have used the code in my scheduler as bellow, it works fine in the 
Extbase version 1.2.1, but it does not work in the new version of 
Extbase (1.3.0beta3)

class Tx_Myextension_Domain_Service_CheckArticleService extends 
tx_scheduler_Task {

	/**
	 * Article->checkArticle
	 *
	 * @return boolean
	 * @see    typo3/sysext/scheduler/tx_scheduler_Task::execute()
	 */
	public function execute() {
		  $configuration = array(
			'pluginName' => 'Pi1',
			'extensionName' => 'myextension',
			'action' => 'checkArticle',
			'controller' => 'Article',
			'switchableControllerActions' => array(
			array('controller' => 'Article', 'action' => 'checkArticle')
			)
			);

			$dispatcher = new Tx_Extbase_Dispatcher();
			$dispatcher->dispatch('', $configuration);
       return true;
}

I have checked the changlog of its extension, it has been changed in the 
Typoscript, but I don't know how to change it in my PHP code. Does 
anyone know how to make it works?

Regards,
Chivy
