Problems with Polyglot 2.0 beta and WPLANG

Hi,
I’m using polyglot 2.0 beta and it seems to work fine when it comes to display the right post content for the selected language. I “gettexted” on a .po and then .mo file the stuff i use for my templates, but i only see it displayed for the language that’s set as default on wp-config.php. Polyglot is supossed to change the actual WPLANG when this is enabled:

$polyglot_settings['lang_change_locale'] = true;

but i’m echoing the WPLANG variable and even if i select a different language with polyglot, it’s still set to the default lang.

this is the code that’s supossed to do the trick:


/*
If the Polyglot is supposed to change the global language settings then... let's do that!
*/
if ($polyglot_settings['lang_change_locale']){

$polyglot_foo = ( isset($polyglot_settings['wplang'][$polyglot_settings['lang_pref']]) ) ? $polyglot_settings['wplang'][$polyglot_settings['lang_pref']] : $polyglot_settings['lang_pref'];

if (!defined('WPLANG')){
define('WPLANG', $polyglot_foo);
}

if($locale != $polyglot_foo){
$locale = $polyglot_foo;

load_default_textdomain();
}
}

return;
}

any ideas on how to get this succefully working?
