passing drupal $language as flashvar (is it a bug?)

Hi,

I did a simple edit at function theme_swfaddress_swfobject from SWFAddress module, to be able to pass the drupal language site as a flashvar for my flex application using modular resource bundles:

global $language;
swfobject.embedSWF("%s%s", "%s", "%s", "%s", "%s", false, {localeChain: $language->language}, {bgcolor: "#%s" , allowFullScreen: "true"}, {id: "%s", name: "%s"});

But i always get the same value, despite the url with other language (eg "carvalhar.com" and "carvalhar.com/fr" has the same null $language->language value).

So...how can i retrieve the language value from drupal and set it in this fucntion? other modules uses as this example, but maybe because it's a theme hook the language is called before it's setted (not sure).

any suggestions?

thanks in advance.
