Hopefully you found your answer, as it took me some serious searching and some combination of code to find this answer, but this is what worked for me:

add_action('restrict_manage_posts','my_restrict_manage_posts');

		function my_restrict_manage_posts() {
			global $typenow;

			if ($typenow=='your_custom_post_type'){
                         $args = array(
                             'show_option_all' => "Show All Categories",
                             'taxonomy'        => 'your_custom_taxonomy',
                             'name'               => 'your_custom_taxonomy'

                         );
				wp_dropdown_categories($args);
                        }
		}
add_action( 'request', 'my_request' );
function my_request($request) {
	if (is_admin() && $GLOBALS['PHP_SELF'] == '/wp-admin/edit.php' && isset($request['post_type']) && $request['post_type']=='your_custom_post_type') {
		$request['term'] = get_term($request['your_custom_taxonomy'],'your_custom_taxonomy')->name;

	}
	return $request;
}

Hopefully this helps, and if anyone has suggestions how to improve it I'd be glad to hear it.

Dalbert, you're a genius. I was looking for this fix for some months now.

I should add a note: if you're using a subfolder for your WP installation, this if statement will not work:
if (is_admin() && $GLOBALS['PHP_SELF'] == '/wp-admin/edit.php' && isset($request['post_type']) && $request['post_type']=='your_custom_post_type') {

ie: my WP it's installed on /test subfolder. so my $GLOBALS['PHP_SELF'] will not be equal to '/wp-admin/edit.php'. It's value will be: '/test/wp-admin/edit.php'
Therefore, the if statement will fail.

A quick fix I add to your code:
```
function my_request($request) {
    $current_url = substr( $GLOBALS['PHP_SELF'], -18);
    print_r ( $current_url );
    if (is_admin() && $current_url == '/wp-admin/edit.php' && isset($request['post_type']) && $request['post_type']=='disenadores') {
        $request['term'] = get_term($request['categoria-diseno'],'categoria-diseno')->name;
        echo 'entré';
    }
    return $request;
}
```
hope it helps

Is there any reason why this would work for some custom post types and not others. I have a total of four custom post types and this works perfect for Events and Success Stories.

Issues:
- On Staff Members it throws a "no ... found" page for one term "Head Coach".
- On WODs I consistently get the "no ... found" page.
For the Head Coach one I thought maybe since it is made up of two words but the url that is created uses the term ID.

functions.php - http://pastie.org/private/nymddfgstu8r7eoaslgaq
post-columns.php (filter code located here) - http://pastie.org/private/yxbtiu3anfmzgexcd5vgsa
taxonomies.php - http://pastie.org/private/ama35mgctl9ycepfyae5bq
post-types.php - http://pastie.org/private/zqziceoctvduldopxlirjq

Thanks

This is perfect !

And you may even add to the $args array the 'selected' param to keep track of the searched term after page reload :

'selected' => $_GET['your_custom_taxonomy']

Thanx a lot for this piece of code :)

I just realized my ammend to dalbert code it's full of echo and stuff.

Also, the check for current_url part seems to be unnecesary:
if (is_admin() && $current_url == '/wp-admin/edit.php' && isset($request['post_type']) && $request['post_type']=='your_custom_post') {

Here's a cleaner version:

function my_request($request) {
if (is_admin() && isset($request['post_type']) && $request['post_type']=='your_custom_post') {
$request['term'] = get_term($request['your_custom_taxonomy'],'your_custom_taxonomy')->name;
}
return $request;
}

Did any of you have a better fix than this? Anyone knows of a plugin with manage this?

I have found somatic's method the best solution as it is compatible with the coming version of 3.1.

I get a fatal error that points to the line: get_term($request['your_custom_taxonomy'],'your_custom_taxonomy')->name;
Is there a typo there somewhere? It's hard to tell!

It depends on the fatal error. Most likely, it's a parse error due to PHP4 (you can't do ->name off a function like that in PHP4).

What is the error?

I tried the code, but its not working for me.... the filter does appears in the control panel in the custom post_type. but when applying the filter, nothing is displayed...
I have no idea what I might do wrong...

add_action('restrict_manage_posts','specials_restrict_manage_posts');
	function specials_restrict_manage_posts() {
		global $typenow;

		if ($typenow=='specials'){
			 $args = array(
				 'show_option_all' => "Show All Categories",
				 'taxonomy'        => 'type',
				 'name'          	=> 'type',
			);

			wp_dropdown_categories($args);
		}
	}

	add_action( 'request', 'my_request' );
	function my_request($request) {

		if (is_admin() && isset($request['post_type']) && $request['post_type']=='specials') {
			$request['term'] = get_term($request['type'],'type')->name;
	}
	return $request;
	}

Here is all the code you need to get this custom post type filter to work:

add_action( 'restrict_manage_posts', 'my_restrict_manage_posts' );
function my_restrict_manage_posts() {
	global $typenow;
	$taxonomy = $typenow.'_type';
	if( $typenow != "page" && $typenow != "post" ){
		$filters = array($taxonomy);
		foreach ($filters as $tax_slug) {
			$tax_obj = get_taxonomy($tax_slug);
			$tax_name = $tax_obj->labels->name;
			$terms = get_terms($tax_slug);
			echo "<select name='$tax_slug' id='$tax_slug' class='postform'>";
			echo "<option value=''>Show All $tax_name</option>";
			foreach ($terms as $term) { echo '<option value='. $term->slug, $_GET[$tax_slug] == $term->slug ? ' selected="selected"' : '','>' . $term->name .' (' . $term->count .')</option>'; }
			echo "</select>";
		}
	}
}

This line: $taxonomy = $typenow.'_type'; has '_type' at the end of it because my custom taxonomy looks like this:

register_taxonomy('event_type','event',create_taxonomy_args('event',true));

So what ever you add on as a suffix (if you do that) you need to change in the code above.
