RSpec 2.0.0.beta.4 stubbing rails controller method issue

I’m trying to stub a controller method using RSpec 2.0.0.beta.4 and
Rails 3 and whenever I attempt to do it I get an error, e.g.

controller.stub!(:current_host).and_return(Factory.build(:host))
post :create

Results in:

Failure/Error: post :create
can't convert nil into String
# (eval):3:in `post'

Removing the stub doesn’t cause the error and the post is fails as
expected. In fact even trying to dump the controller before the post
causes this error (as I wasn’t sure if it was still controller or had
been moved to an instance variable).

Controller specs are currently built on rails integration test
behaviour. We’re going to change that so it’s built on rails functional
test behaviour and that will solve your issue, but I’m not sure when
that will happen. Definitely before final releases of both rspec-2 and
rails-3, but there are lots of priorities being juggled in both
projects.

Please feel free to raise rspec-2 issues in the appropriate repo in
github. In this case: Issues · rspec/rspec-rails · GitHub.

Thanks!
