Question: Any help regarding usage of the NSSharingService (composeEmail)

[de-robat]

Hello, first of all - thanks for this library! I'm rather new within the Objective-C realm and therefore may have a fairly "dump" question. I managed to get the following code running within X-Code:

NSSharingService* mailShare = [NSSharingService sharingServiceNamed:NSSharingServiceNameComposeEmail];
NSLog(@"canPerform %@", [mailShare canPerformWithItems:nil] ? @"YES" : @"NO");
[mailShare performWithItems:nil];

This prints out canPerform YES, and opens the Users default Mail-Application.

But i cant make the same code work form node.js. Is my adaption to the syntax of NodObjC correct after all?

var mailShare = $.NSSharingService('sharingServiceNamed',$.NSSharingServiceNameComposeEmail);
console.log("canPerform", mailShare('canPerformWithItems',$.nil));
mailShare('performWithItems', $.nil);

This prints out canPerform true, and then nothing else happens. What am i doing wrong?
Any help is greatly appreciated!

(source code simplified for the sake of clarity, im attaching files and adding in a mail body in the concrete implementation)

Edit: Additional Information I tried adding my code into a self compiled Framework, just as showcased in this repo (Test-Framework). That yielded exactly the same result. I get the Print-Out canPerform YES but the Mail-Client is not launched. So that at least eliminates the possibility of me screwing up the translation for Objective-C to the NodObjC syntax or does it? Is this somehow a rights issue?
