ZF1 and ZF2 are very different in terms of their architecture. ZF2 is event driven; meaning that you will need to attach an event listener to the controller dispatch event or order for it to correctly set the layout.
class Module
{
public function getControllerConfig()
{
return array(
'factories' => array(
'Namespace\Controller\Ajax' => function($cpm) {
$controller = new Namespace\Controller\Ajax();
$eventManager = $controller->getEventManager();
$eventManager->attach('dispatch', function($event) {
// Set layout or perform actions prior to dispatch
$controller = $event->getTarget(); // Controller
$controller->layout('foo/bar');
});
return $controller;
},
),
);
}
