I am currently creating a portal type website. We have created several custom post types such as wiki, and project which each have their own taxonomies, but they also include the WordPress post_tags, and such. Running the default WordPress tag cloud yields the correct count when hovering over a tag (for example it says 3 posts of category QOTC) however, once you click on it you receive a page where nothing is found unless the category was linked to a post. I have searched through the default-widget.php file and the post-template.php file to no avail. Does anyone know how to make the custom post types display on the output page for the tag cloud? Thanks in advanced.
