[Swfdec] problems to lookup AS object properties using SWFDEC API functions

[Bernd Kischnick]

Hello list,

I'm scratching my head over mysterious difficulties with variable lookup
on Swfdec AS-objects inside the library. Neither
swfdec_as_object_has_variable() nor swfdec_as_object_get_variable() nor
swfdec_as_object_get_variable_and_flags() are able to find a property
which definitely exists.

In ActionScript, I'm doing this:

var o = new Object ();
o.foo = "bar";
o.observeValueForKeyPath = function () {...}

I can enumerate this object from Actionscript:
for (p in o) { trace("o["+p+"] = "+ o[p]); }

and Swfdec reliably produces the correct trace output:
o[foo] = bar
o[observeValueForKeyPath]=[type Function]


I can repeat this inside the library, given the pointer to the AS object:

gboolean my_foreach (SwfdecAsObject *object,
    const char *variable, SwfdecAsValue *value, guint flags, gpointer data)
{
  const char* val = swfdec_as_value_to_string (data, value);
  SWFDEC_ERROR("object @%p [%s] = @%p ('%s')", object, variable, value, val);
  return TRUE;
}

/* SwfdecAsContext *cx, SwfdecAsObject *object */
  swfdec_as_object_foreach (object, my_foreach, cx);

This way the properties 'foo' and 'observeValueForKeyPath' are found,
additionally '__proto__' and '__constructor__'.

But when I try to look up 'foo' or 'observeValueForKeyPath' using
swfdec_as_object_has_variable(),
swfdec_as_object_get_variable(), or
swfdec_as_object_get_variable_and_flags()
with parameter 'variable' set to the property name, neither of them succeeds.

What am I doing wrong???

confused,
