I don't really know where to file this; it's an interaction between env.js and Rails, basically, but it bit me in a Capybara context.

I have a Cucumber scenario that fills out a simple form, attaches a JPEG file to the form input, and submits it. It passes in Rack::Test, but when I submit the form using env.js, I get a lot of "Exception while dispatching events: super: no superclass method `require' for Object:Class" (stack trace below).

The offending line is in form.js:

            if (transfer_encoding === "base64") {
                Ruby.require("base64");
                content = Ruby.eval("lambda { |fn| Base64.encode64(File.read(fn)) }").call(array[i].filename);
            }

The 'require' is handled (intercepted?) by ActiveSupport::Dependencies::Loadable:

  def require(file, *)
    load_dependency(file) { super }
  end

... which fails because Object has no superclass, I guess.

I can imagine considering this a bug in Rails, but I'm not sure. It looks like I can work around it by uploading PNGs (this theory is untested), or at a mild performance cost, capybara-envjs could require base64 preemptively instead of waiting for form.js to do it. But maybe there's a better way?

I'm using, among other things, ruby 1.8.7-p299, rails 3.0.3, capybara 0.4.0, capybara-envjs 0.4.0, johnson 2.0.0pre3, envjs 0.3.8, and cucumber 0.10.0.

This seems to work, if inelegantly:

                // Ruby.Object.require("base64");
                content = Ruby.eval("Object.require('base64'); lambda { |fn| Base64.encode64(File.read(fn)) }").call(array[i].filename);

Any chance you could push a test case somewhere?
