Ace editor, javascript flavor: "Failed to load script" exception

Question

I try to use the Ace editor with javascript highlighting, like this:

editor.getSession().setMode("ace/mode/javascript");

"editor" is a valid editor instance, working with PHP or C#. However, from this line I get an exception, what shows up on the Firebug console like this:

uncaught exception: [xpconnect wrapped native prototype]

Failed to load script: http://d1n0x3qji82z53.cloudfront.net/src-min-noconflict/worker-javascript.js (nsresult = 0x805303f4)

I'm using the CDN version of the editor, that's why the cloudfront url. Basically my code is the same as in the Ace embedding sample.

What is going wrong? Any help would be appreciated.

I'm actually getting the same thing.. did you every find an actual resolution to this? Was the fix just 'sucking it up and downloading the library instead of using off the cdn'? — Stephen

Actually it was simpler than that: I asked this question because ACE was not loading for me because of this exception. After a while (like two days) it was loading again, although the exception remained (I don't know if there was a change in code). So all in all the editor works for me fully, but throws this exception... — Piedone

Thanks! But it's strange: when I opened this question the script failed with this exception, now I get it too, but the script runs. Anyway, I guess having this exception is not a good thing, right? :-)
