I'm tring to launch from my app the WebOS memos app. I've tried something like that but it doesn't work. I didn't find anything in services SDK app

Code:
this.controller.serviceRequest('palm://com.palm.applicationManager', {
					method: 'open',
					parameters: {
						id: "com.palm.app.memos",
						params: {  }
					},
					onFailure: function(response) {
						Mojo.Log.error("Seed Status Failure: %j", response.errorText);
					}
				});
It's the same code than the one to launch email or messaging. I've just replaced com.palm.app.memos

And what are the parameters to insert text in the memo ?

Thanks for help !
