XILI language plugin – filter posts in slider

Hi,
I have an issue with XILI plugin – I’ve tried to add this plugin to my website http://www.jirimanek.cz.

I have no problem to change the navigation to link the correct language content, however I’m not able to filter posts in slider. on XILI forums I’ve found that to filter the posts you need to add ‘lang’ => the_curlang() to the $args section where it is called for the view. So this looks like now:
<?php
global $wp_query, $query_string;
$paged = get_query_var( ‘paged’ );
$args = array(
‘posts_per_page’ => 4,
‘paged’ => $paged,
‘ignore_sticky_posts’ => 1,
‘lang’ => the_curlang()
);
$args = wp_parse_args( $args, $wp_query->query );
?>

However it doesn’t filter. Is there any other place which is used to call the slider posts, where I need to change it?

Many thanks,
Jiri

PS: WPML can do this?
