In Ember.js, how does a model recover from a request error?

I am building an ember.js web app with user registration. If the registration fails (e.g invalid email) the API returns an error. The problem is this puts the model into an error state and if the user trys to make another attempt at registering, Ember.js raiser an error Uncaught Error: Attempted to handle event 'willSetProperty' on <App.User:ember451:null> while in state rootState.error. and then seems to become unresponsive.

Do I have to manually reset the state after the error?

becameInvalid: function() {
    // reset the state after an error
    var parentState = this.get('stateManager').get('currentState').parentState.dirtyType;
    if (parentState === "updated") {
      this.get('stateManager').transitionTo('loaded.updated');
    } else {
      this.get('stateManager').transitionTo('loaded.created.uncommitted');
    }

  }

This seems kind of strange. Have I set this up incorrectly? Is there another way or should I reset after errors?

Yes.

Agreed. For sure it will be improved in future versions of ember-data.

Nope, you did it right

Is there another way or should I reset after errors?

No other way AFAIK.

See this post: Ember: transaction.commit does not fire after becameInvalid event

You'd have to manually reset the state. Ember itself doesn't deal with model management. Ember-Data and Ember-Model (which are separate from Ember), have the ability to rollback/revert "dirty" models.
