I create a new rails for testing and I'm having the same problem, but I
have other rails app that work perfectly, with 2.2.2 and with 2.3.2.
If I change the name of the application_controller I get the normal
uninitialized constant ApplicationController
But in the app that I'm having problems, no matter wich name my
Application controller has, I never get this error, and the methods
defined there never fire ...
What do you mean by never fire ? Also be aware of the fact that the
file that rails looks for application_controller in changed in 2.3.2
from application.rb to application_controller.rb
