Look again. Every example on that page with :locals, explicitly specifies
:partial.

Your way isn't working. How about trying something different. The only way
you will find out if the Rails 2 convention, locals only for partials, is or
isn't true in Rails 3 is trying it. You have shown that without :partial and
possibly some other factor, locals don't work. Change only one thing and run
the experiment again.
