Ember throws an error because of Handlebars, which is correct version

Question

Here's the <head> of my HTML document.

<!DOCTYPE html>
<html lang='en'>
  <head>
    <link href="/assets/application.css?body=1" media="all" rel="stylesheet" type="text/css" />
    <script src="/assets/modernizr.js?body=1" type="text/javascript"></script>
    <script src="/assets/jquery.js?body=1" type="text/javascript"></script>
    <script src="/assets/handlebars.js?body=1" type="text/javascript"></script><!-- 1.0.0-rc4 -->
    <script src="/assets/ember.js?body=1" type="text/javascript"></script><!-- 1.0.0-rc3 -->
    <script src="/assets/ember-data.js?body=1" type="text/javascript"></script>

As far as I know, I've put them in the correct order. Ember throws this error:

assertion failed: Ember Handlebars requires Handlebars 1.0.0-rc.3 or greater.

But I've included Handlebars 1.0.0-rc4, which should work, according to this error.

I'm getting Handlebars through the handlebars-assets gem, but that shouldn't matter, since it's supposedly the correct version, right?

Following this SO post's suggestion, I ran rm -rf tmp, and restarted my server, to no avail.

I also tried deleting the handlebars-assets gem and manually including Handlebars 1.0.0-rc4. Same thing.

I tried my best to get a working jsfiddle, but it's not working (apparently because I did it wrong, not related to this issue): it's here.

Can you recreate the issue in a jsfiddle perhaps? (You can load external scripts on the side), I've seen this in a script order issue before, but your order seems ok. — Benjamin Gruenbaum
I tried to get one, but I'm new to Handlebars and Ember, so it's not working, but not because of this problem. It's here. — nickcoxdotme
That seems to work jsfiddle.net/cz3Xv/1 (you forgot to run the script on-dom-loaded) — Benjamin Gruenbaum
You're right. That does seem to work. I wonder what it is, then, if those same versions are in my app. — nickcoxdotme

The problem seams to be that you are using the wrong ember/handlebars files combinations.

assertion failed: Ember Handlebars requires Handlebars 1.0.0-rc.3 or greater. But I've included Handlebars 1.0.0-rc4, which should work, according to this error.

As far I can see with this PR in the ember-latest this has been fixed. This should work:

you can get here the latest builds: http://builds.emberjs.com

hope it helps
