Sandboxing, login items and launch App

Question

Trying to make my app works with sandboxing I get stuck in this problem:

I need to add my App to login items so I've followed these steps:

• Creating an HelperApp.app (with is agent = YES) that at the open exec this code :

  NSString *appPath = @"/Applications/MyNewApp.app";
  [[NSWorkspace sharedWorkspace] launchApplication:appPath];
  [NSApp terminate:nil];
  

  This app is sandboxed.

• I added a copy build phase to my MyNewApp.app bundle with subpath Contents/Library/LoginItems and destination wrapper

  And obviously also the MyNewApp.app is sandboxed

• In MyNewApp.app I registered with SMLoginItemSetEnabled the bundle id for the HelperApp.app

Now all works correctly but... when MyNewApp.app tries to launch MyNewApp.app I get an error:

LSOpenFromURLSpec() returned -10827 for application /Applications/MyNewApp.app path (null).

But if I try to use the HelperApp.app to launch a not sandboxed (i.e. Steam.app) app it works like a charm!

Is there another way to launch the app? probably NSWorkSpace works with functions not allowed in sandbox context. What do you suggest?
