register_post_type, hierarchical not working

Hi all, this is my first post, so please forgive me if I don’t conform to the board norms ??

I am registering a custom post type using register_post_type. I want this post type to more or less act like a page (e.g. I need to be able to set a theme and assign a parent).

Here is the call I am making to register_post_type:

register_post_type('foo', array(
	'labels' => array(
		'name' => 'Foo',
		'singular_name' => 'Foo'
	),
	'description' => 'A Foo',
	'public' => true,
	'supports' => array(
		'title', 'editor', 'author', 'page-attributes'
	),
	'show_ui' => true,
	'hierarchical' => true,
	'menu_position' => 20,
	'capability_type' => 'page'
));

Now, this works with the exception that the only page attribute I am seeing when I go to add a new post is “order”. I don’t see the “Parent” and “Theme” drop downs like I would with a normal page.

As you can see above, I specifically set “hierarchical” to true and it was my understanding from the codex that this was all that was required.
