With Display Suite Extra, we can turn on the View mode switcher which allows site visitor to view different view mode of a content type ajaxly.

 

Now i got 2 views blocks with nid being set as contextual filter. I have added the 2 blocks on 2 different view modes and I expect the blocks will only show the content of the current node. But when the other view mode is loaded thru Ajax, it the the contextual filter doesn’t work.

One workaround is to get the nid from the url and set it as the default input of the contextual nid filter.

// Get the nid from the ajax call request
if (isset($_GET["id"])) {
  return $_GET["id"];
}
return null;

Done =)
