Ember doc as of last week was base on RC3 or something while I was using RC7. Wtf. I followed the tutorial with RC3 and some emberdata version that was included in the tutorial. Switch to RC7 everything break. The error response was gibberish, had to stack trace it, to find out I need to switch emberdata to the newest version. I don't get why people keep on saying AngularJS doc is bad. Maybe I'm weird but I've found Ember JS to be horrible and AngularJS to be very good.
