Like the title says capybara is having trouble finding double_click:
undefined method `double_click' for #<Capybara::Node::Element:...>
Click works just fine as do most other methods. I'm using capybara 2.1.0, poltergeist 1.6.0 and phantomjs 1.9.7. Any ideas?
For posterity here's the solution:
I set javascript_driver:
Capybara.javascript_driver = :poltergeist
but not default_driver:
Capybara.default_driver = :poltergeist
