I am writing a flex app and the following code returns the token and surface for each surface correctly logged under the application myspace account. However, when I  add developers, the canvas and profile iframes return their unique tokens and expected surface, but for home it returns null for both the token and surface for those developers who add the app.

 osToken = Application.application.parameters.opensocial_token;
 osSurfaceName = Application.application.parameters.opensocial_surface;
