[Plugin: Posts 2 Posts] Can't get example to work

Hi,

Thanks for another great plugin, the possibilities of P2P are great. But I’m having some trouble making it work.

I did the following, on a blank WP (3.1.1) and P2P (0.7), my PHP version is 5.3.3 :

Created a custom post type named : publications

Then in functions.php :

function my_connection_types() {
	if ( !function_exists( 'p2p_register_connection_type' ) )
		return;

	p2p_register_connection_type( array(
		'from' => 'publications',
		'to' => 'page'
	) );
}
add_action( 'init', 'my_connection_types', 100 );

and in page.php :

$connected = new WP_Query( array(
	'post_type' => 'publications',
	'connected_from' => get_queried_object_id()
) );

echo '<p>Related posts:</p>';
echo '<ul>';
	while( $connected->have_posts() ) : $connected->the_post();
		echo '<li>';
		the_title();
		echo '</li>';
	endwhile;
echo '</ul>';

wp_reset_postdata();

This is exactly the examples from the wiki, I just adapted it to a custom post type. But it doesn’t work, all it shows is : “Related posts:”

Am I missing something ?
