I'm having issues with this. I have 2 while loops, each getting different custom post types. They both work fine, except, my sidebar content i.e. widgets, is not appearing. I think this is because I am not running the default query.
My two queries are:
query_posts('post_type=offered'); while (have_posts()) : the_post(); ?> ....content endwhile;
$wanted_query = new WP_Query('post_type=wanted'); while ($wanted_query->have_posts()) : $wanted_query->the_post(); ....content endwhile;
However, when I try to combine them as below, I get the sidebar content but no my posts!
global $query_string; query_posts( $query_string . '&post_type=offered' );
