After upgrade to 3 from 1 layout method doesn't render anything...

I'm upgrading to Rails 3 from version 1. It has gone incredibly
smooth. Thanks Rails Core!

I am not working with a restful app, not even close. RESTfully,
everything works as expected.

Nothing renders when I call layout 'main', unless I render on a per
action basis with render :layout => 'main'.

This is a lot of duplication, not to mention the double render
fiasco.

Is there any advice, other than rewrite this app the RESTful way?

Thanks,

Steve
