Rewriting a custom-post-type permalink with taxonomy term?

Question

I'm trying to rewrite my url for a custom_post_type named wr_events with one of its custom_taxonomy terms from event_type

add_action('init', 'wr_events');

function wr_events() {

     register_taxonomy(
        'event_type',
        'wr_event',
        array(
            'label' => 'Types',
            'singular_label' => 'Typ',
            'hierarchical' => true,
            'query_var' => true,
            'rewrite' => array('slug' => 'events'),
        )
    );

    $labels = array(
        'name' => _x('Events', 'post type general name'),
        'singular_name' => _x('Event', 'post type singular name')
    );

    $args = array(
        'labels' => $labels,
        'public' => true,
        'publicly_queryable' => true,
        'show_ui' => true,
        'query_var' => true,
        'capability_type' => 'post',
        'hierarchical' => false,
        'menu_position' => null,
        'supports' => array('title','editor','thumbnail', 'excerpt'),
        'rewrite' => array(
            //'slug' => 'event',
            'slug' => 'events/%event%',
            'with_front' => false
        ),
        'has_archive' => 'events'
    ); 

    register_post_type( 'wr_event' , $args );
    flush_rewrite_rules();
}

add_action('save_post', 'save_details');

add_filter('post_type_link', 'events_permalink_structure', 10, 4);
function events_permalink_structure($post_link, $post, $leavename, $sample)
{
    if ( false !== strpos( $post_link, '%event%' ) ) {
        $event_type_term = get_the_terms( $post->ID, 'event_type' );
        $post_link = str_replace( '%event%', array_pop( $event_type_term )->slug, $post_link );
    }
    return $post_link;
}

So in my case my taxonomy terms would be "workshops" or "lectures" etc. url/events/lectures or url/events/workshops lists all my posts related to this "category", url/events shows a custom archive for all my events. -> this is just what I want however the only thing not working is the complete url to the custom-post itself …

url/events/lectures/post-name - throws a 404!

Any idea why this is happening? My events_permalink_structure() function seems to work correctly as it replaces my permalinks exaclty the way I want.

I installed the "Rewrite Analyzer" Plugin and it shows me "Regex is empty" for wr_event -> http://bit.ly/HN8vbS

I've also tried to flush the Rewrite Rules by visiting the permalink settings. However no effect.

Please guys help as I'd love to have this feature. Thank you in advance.

Change all your %event% to %event_type%. I hope that works for you.
