Ember Data Errors

When using the latest ember-data and latest easyForm, both built from master, I get the following error:

    Uncaught TypeError: Cannot call method 'get' of null ember-easyForm.js:305

EasyForm checks if errors is undefined but DS.Model is initialised with errors as null.

    DS.Model = Ember.Object.extend(Ember.Evented, LoadPromise, {
      ...
      errors: null,
      ...
    });

Checking if errors is truthy seems to solve the issue for me and all tests still pass. Not sure how this will affect ember-validations.
