            }
 
        };
 
		greetingService.findAllEvents(callback);
		return records;
	}
}

la ListGrid reste toujours vide, et celà que j'utilise RPC ou RequestFactory.
le traitement du callback s'efféctue après celui de l'affichage de la ListGrid et même après rien ne s'affiche dans la Grid
SVP pouvez vous m'aider ?

fallait just mettre le setData dans le onSuccess
