Swfdec - Feb 2010 - AS context->global not an object problem

Hi, another quick question,

Im trying to set a variable within the flash movie at runtime. Im trying to set
the variable triggered by fscommand, the code im using so far is...

static void
do_fscommand (SwfdecPlayer *player, const char *command, const char *value)
{
   SwfdecAsValue val;
   SwfdecAsContext *context;

   if (g_str_equal (command, "test")) {
     context = SWFDEC_AS_CONTEXT (player);
     SWFDEC_AS_VALUE_SET_STRING (&val, "success!");
     swfdec_as_object_set_variable (context->global,
swfdec_as_context_get_string (context, "teststring"), &val);
   }
}

Firstly, im not sure if this is the correct approach, but more importantly it
fails because there appears to be no global object. Ive tested that the
context is in a running state which it is, plus ive tried sticking similar code
in swfdec_as_context_startup which works ok, so i know context->global
is valid at this point. Im guessing theres something fundamental im not
understanding!

Im hoping someone can help shed some light :)
Thanx, Paul

Yeah, this is one of the places where something nonobvious happens.
SwfdecPlayer unsets the current global object unless it is actually
executing code. This is because multiple global objects can exist at
the same time due to the Flash security model (feel free to google it
up, I'm not gonna get into details).
The internal Swfdec code uses the functions
swfdec_sandbox_use()/swfdec_sandbox_unuse(), but they are not exported
as public API.
So I don't think there's any chance for a user of the public API to
modify the state of the Flash player currently. Certainly the
SwfdecAsContext APIs don't work.
