DigitalFormula on "How to add shortcodes to PHP namespace"

Hi all,

All my theme and plugin classes are part of my custom namespace, except for the shortcodes.

The classes have standard PHP __construct() methods that call methods like register_nav_menu(), for example. They work fine.

However, when I modify my shortcode file so that it's part of my namespace and call add_shortcode() in the constructor, the shortcodes no longer work - they just display the [shortcode params=""] markup. If the file isn't part of the namespace and I call add_shortcode() at the end of the file, they work fine.

Here's one of the add_shortcode() calls:

add_shortcode( 'social', 'social_shortcode');

The function's code is like this (with all the main parts removed as they aren't relevant):

function social_shortcode( $atts )
{
   /* do shortcode stuff here */
}

Is there a special way of calling add_shortcode() when the file is part of a namespace? If not, what am I doing wrong?

I've selected 3.7.1 as the WP version, although I'm using 3.8-beta1. The results are the same if I test the code on a production 3.7.1 site, though.
