Re: out parameters in seed

[Jonh Wendell <jwendell gnome org>]

Thanks, Alan.

I've tried both:

  a = am.get_most_available_presence (b);
  print (b.status);
  print (b.message);

  a = am.get_most_available_presence (b, c);
  print (b.value);
  print (c.value);

They give me the same error:
** (seed:3138): WARNING **: Exception in closure marshal. Line 17 in
test1.js: TypeError Result of expression 'b' [undefined] is not an
object.

The C signature for the function is
http://telepathy.freedesktop.org/doc/telepathy-glib/telepathy-glib-account-manager.html#tp-account-manager-get-most-available-presence

Any other hint?
