Cannot fill test data into a form with rspec, capybara and selenium

Question

I'm testing my Ruby on Rails 3.2 App with RSpec, Capybara and Selenium (Used driver: webkit and poltergeist).

I will try testing the following code:

scenario 'ask a question', js: true do
  visit group_path(@group, locale: 'en')

  find('#question_subject').set 'A new question'
  find('#question_content').set 'The content of the question'
  find('#question_tag_tokens', visible: false).set @tag.id

  find('#submit').click

  expect(page).to have_content 'A new question'
end

But when I try to run the test I will receive the following error:

 1) Interact with group ask a question
 Failure/Error: find('#question_subject').set 'A new question'
 Selenium::WebDriver::Error::JavascriptError:
   waiting for evaluate.js load failed

 # ./spec/features/groups_spec.rb:93:in `block (2 levels) in <top (required)>

In the spec_helper.rb file has additional lines for DatabaseCleaner:

config.use_transactional_fixtures = false

config.before(:suite) do
  DatabaseCleaner.clean_with :truncation
end

config.before(:each) do
  if example.metadata[:js]
    DatabaseCleaner.strategy = :truncation
  else
    DatabaseCleaner.strategy = :transaction
  end
  DatabaseCleaner.start
end

config.after(:each) do
  DatabaseCleaner.clean
end

I cannot solve this issue. I was trying different drivers for testing javascript: poltergeist and capybara-webkit. But I get the same error. Hope you can help me.

I solved my own problem by using the chromedriver for testing:

Download the chromedriver.
In my case I moved the chromedriver executable into /usr/local/bin/ and added this location to my $PATH variable: export PATH=/usr/local/bin/;$PATH
Add following lines to your spec/spec_helper.rb file (capybara wiki):

Capybara.register_driver :selenium do |app| Capybara::Selenium::Driver.new(app, :browser => :chrome) end

Update:

The chromedriver caused a new problem: Not finding the hidden elements. So I installed capybara-webkit and now it all works fine.
