I guess I misunderstood what you're trying to do. If you're talking
about the category widget that prints wp_dropdown_categories(), you'll
need to redefine that widget with wp_dropdown_categories() such that
its "hide_empty" argument is set to 0.
The reason is that by default "hide_empty" is true, meaning that only
those categories will show up that have a positive count of associated
objects. For each taxonomy, that count gets incremented by a callback
as determined when the taxonomy is defined. For example, the
"category" taxonomy for object_type "post" calls
"_update_post_term_count" as the "update_count_callback." Since each
taxonomy specifies its object type and you're using a custom object
type, probably there is no associated "update_count_callback," and the
count stays at zero.
