Error when rendering 2 models for a template in Ember.js

I have a template in wish I have 2 components that represents different Models. I need to create a model that contains both datas, for each component. If I have only one model everything works fine, but when I add other one, then this error happens in the console.

Error while processing route: events record is undefined ember$data$lib$system$store$finders$$_find/</<@http://localhost:1361/test/frontend/bower_components/ember-data/ember-data.prod.js:7475:11

The route of the template that contains the components is:

App.EventsRoute = Ember.Route.extend({
    model: function()
    {
        return Ember.RSVP.hash({
            event:  this.store.find('event'),
            featured: this.store.find('event', 'featured')
        });
    }

});

Does anyone knows why this error happens and what can I do to solve it?
