Sprockets::FileNotFound thrown if component includes external CSS

[rootpd]

I've installed Polymer/paper-button component from bower
( bower install Polymer/paper-button )
which includes Google's web font in CSS.

When evaluating external link, Sprockets::FileNotFound is being thrown. If local CSS is used, it works as expected.

Link tag which throws the error:

<!-- app/assets/components/font-roboto\roboto.html -->
<link href='//fonts.googleapis.com/css?family=RobotoDraft:regular,bold,italic,thin,light,bolditalic,black,medium&lang=en' rel='stylesheet' type='text/css'>

Can you please provide the full error message you get from rails? For instance, for me it would look like:

couldn't find file '/Users/andrew/Documents/rails/emcee_test/app/assets/components/test/http:/fonts.googleapis.com/css?family=RobotoDraft:regular,bold,italic,thin,light,bolditalic,black,medium&lang=en'
  (in /Users/andrew/Documents/rails/emcee_test/app/assets/components/test/test.html)

I want to see what path it's looking at.

Thanks!

Thanks, although I just realized that the path is not the issue. The problem is that Sprockets isn't designed to work with external content like that. I'm going to work on not trying to inline external content, and should have something working soon.

[ahuth]

@rootpd, this has been fixed in master, although it hasn't made it to a release, yet.

Now, when Emcee see's an external reference to a stylesheet, it doesn't attempt to inline it. If you get a chance, test this out and let me know that it works for you.

Thanks!
