Nested Routing in Rails 3.0 results in "route set not finalized" error

Created a new project and in it two models: conferences and events. I then nested events below conferences in my routes.rb file and in testing it all seemed to work until I tried creating any new events or editing existing events below conferences and would repeatedly get "route not found" errors for the POST request. None of the member functions for update or create were even being reached.

Since |resources| takes care of the generation of all those paths, this made no sense. Afterward I used 'rake routes' to determine all the known routes of which |update| and |create| did appear correctly.

I went further and entered the 'rails console' and assigned the router to a variable to interrogate the known paths. Printing the known routes was successful however any use of |recognize_path| or |generate| on the Routing object resulted in a "route set not finalized" error.

There's something in the bowels of the routing system that is not working properly but is working well enough until you need to do create/update operations or introspect the object.
