[REGRESSION] In Ember 1.13.0+ initial literal values of component attributes cannot be updated

[OrKoN]

See jsbin http://emberjs.jsbin.com/likiqofaxa/1/edit?html,js,console,output

If you pass a literal as an attribute value, the component cannot update it:

    {{my-component test="initial-value"}}
    {{my-component}}

where MyComponent is

var MyComponent = Ember.Component.extend({
  test: null,
  init: function() {
    this._super();
    this.set('test', 'updated');
  }
});

The first does not work(test is not updated in the component template) and the second works as expected.

I am migrating from 1.12. jsbin http://emberjs.jsbin.com/tuhisokijo/1/edit?html,js,console,output

i would assume:

this.set('test', this.get('test') || 'updated');

would be the way to deal with defaults in init

[OrKoN]

@stefanpenner the problem is that one cannot override the defaults

[rwjblue]

Submitted #11572 to address this.

[OrKoN]

@rwjblue Thanks a lot! Will the fix appear in the 1.13.3 release? When may I expect it?

[rwjblue]

Yes, it will be in 1.13.3 (should be out in a day or two).

@rwjblue @stefanpenner This is happening again in Ember 2.1.0 (regression compared to 2.0.2) http://emberjs.jsbin.com/yinuqe/edit?html,js,console,output

@OrKoN - Can you open a new issue?

[OrKoN]

@rwjblue sure, opened a new one
