menu needs to offer Primary and Secondary links blocks

Looks good and works fine.

Indeed, quite simple. Committed, thanks!

I'd like to reopen this issue, while i think this is not the best idea. I know this was the way how it has worked in past, but as a theme developer i'm often asked by people why they are unable to position the secondary menu with block configuration. What I'm said is simple - "don't use block configuration to assign primary and secondary menus to a region" with the comment that "this are very special menu types that are hardcoded in the themes". And this is why i think it's better to not allow this per default - or give theme developers the ability to disable primary and/or seconday menus via the themes .info file.

Please let's discuss how we can solved this problems... maybe we should open a new case about this.

Ups, missed something important... I meen:

...give theme developers the ability to disable primary and/or secondary menu assignment in blocks configuration. This could be done via a themes .info file setting.

This issue deals with a bug. It restores functionality that was temporarily lost during the 5.x to 6.x menu transition. It is now fixed.

If you would like to discuss features involving theming and menus, please open a separate issue.
