RubyMine 1.5 disallows to create Test::Unit run configuration for functional tests

Hello,

  In my project, 'test' folder is marked as test source. I use simple plain rails functional tests (Test::Unit), which start like this:

require File.dirname(__FILE__) + '/../test_helper'
class NotificationsTest < ActionController::TestCase
...

  RubyMine 1.5 disallows me to create a run configuration from NotificationsTest test class (it is located under 'functional' folder).The same applies for other functional tests.
  On the other hand, I can create notifications from unit tests (which located under 'unit' directory).

  My functional tests are not listed if I invoke class chooser to choose a class to test.

   Is this a know problem?

   Regards,
