[Plugin: Posts 2 Posts] Get comments of connected posts ?

That’s because wp_list_comments() is lame and retrieves the comments from $wp_query->comments, instead of checking the $post global.

There’s nothing wrong with your code or with P2P, but it seems you will need to do some ugly workarounds to make it work (I’ve never tried it before).

Oh too bad… so nothing possible ?

Finally, I’ll show them using a Fancybox effect loading their own single_CPT.php… ??
