requiring javascript_helper outside rails December 30, 2008

I wanted to fix the tests for css_browser_selector, when updating it to support a rails 2.2.0 change with concat.

However, I would get the following error.

>> require 'action_view/helpers/javascript_helper'
TypeError: wrong argument type Symbol (expected Proc)

As it turns out you must require ActiveSupport first, since the JavaScriptHelper requires Sym#to_proc.

Also, ActionView::Helpers::JavascriptHelper alias was removed – yay tests!
