[Radiant] Difference between development/production environments from extensions point of view

[13]

Hi,

I'm developing a new extension for radiant. I have created a
controller which is a subclass of Admin::AbstractModelController like
this:

class PostsController < Admin::AbstractModelController
  model_class Post
  # ...
end

Posts controller is mapped to a new tab in the admin interface. When I
click this tab list of items is displayed.

In development environment everything is working as I want, but when I
try to run the same extension in production environment I get
following error:

uninitialized constant Admin::PostsController

I checked environment specific configuration files, but haven't found
anything suspicions.

Any help on how to fix this issue will be appreciated.
