Could be timing issues. I've tried to put a lot of waiting_for around ajax and jquery animation stuff. It runs on my laptop and my server without problems, so I am curious why it doesn't run all green for you...

Tag view btw is a view on todos (with specific tags), but not a view on tags, so I found it to be closer to TodosController than TagController.
Another option is to move stuff like tags and dependencies so separate modules, so the related code is together in one rb file, and it is merged into one controller. I like the book Refactoring Ruby Edition :-)
