ES5 getters on an Ember.Object only ever return first computed value

[chrisjshull]

var i = 0;
var obj = Ember.Object.extend({
    get index() {
        return i++;
    }
}).create();
console.log(obj.index); // 0
console.log(obj.index); // 0 -> should be 1

Compare to not extending Ember.Object:

var i = 0;
var obj = {
    get index() {
        return i++;
    }
};
console.log(obj.index); // 0
console.log(obj.index); // 1

Ember 2.3.0

Oh, and just in case people were curious, using .get doesn't help:

var i = 0;
var obj = Ember.Object.extend({
    get index() {
        return i++;
    }
}).create();
console.log(obj.get('index')); // 0
console.log(obj.get('index')); // 0

I wouldn't expect it to though. It looks like Ember is doing a 1-time evaluation of the property at mergeMixins time. Anything after that resolves to that "cached" value.

#12491

I believe it is also included in 2.4.0-beta.2

Can we reopen this? The snippet above is not fixed (Ember 2.8.0).
