CodeExtinguisher Release Candidate 11

Is this the way the ManyToMany is supposed to work?

got 3 tables in my DB:

Code:

CREATE TABLE `articles` (
  `id` int(5) unsigned NOT NULL auto_increment,
  `date` date NOT NULL,
  `title` varchar(255) NOT NULL,
  `body` text NOT NULL,
  `excerpt` text NOT NULL,
  PRIMARY KEY  (`id`)
)

CREATE TABLE `tags` (
  `id` int(11) unsigned NOT NULL auto_increment,
  `name` varchar(255) NOT NULL,
  PRIMARY KEY  (`id`)
)

CREATE TABLE `articles_tags` (
  `id` int(11) unsigned NOT NULL auto_increment,
  `articles_id` int(5) NOT NULL,
  `tags_id` int(11) NOT NULL,
  PRIMARY KEY  (`id`)
)

I got that in my articles YAML:

Code:

tags:
        class: ManyToMany
        params:
            display_field: name

Everything works fine, but when I add a tag to an article, with the arrow button to put it from left to right box, next time I open that same entry, the tag is present in both sides so I can add the same tag over and over to the same entry and it will create "duplicates" in my "articles_tags" table. shouldn't the tag be gone from left box if already assigned in right box?

Also, as a side not, those boxes should probably labeled with add/remove out of the box for usability sakes. a detail really...

Thanks!
