simulate store.find for non ember models

snippet

_findCountries: ->
  isoCodes = Ember.Object.createWithMixins(IsoCodes)

  countries = (Ember.Object.create({ id: code, name: name }) for code, name of isoCodes.isoCountries)

  promise = Ember.RSVP.Promise.resolve(countries)
  promiseArray = Ember.ArrayProxy.extend(Ember.PromiseProxyMixin)

  promiseArray.create({ promise: promise })

I've a list of countries which are not stored in the store and so there is no 'real' ember-data model for it.

This list is used for a selectize box which is rendered dynamically and all other models are fetched from the store via .find. What I'm trying to archive is to return the same structure as I get with store.find(). The result needs to be a promise and it has to have a content.

this returns me an array not an object with a content attribute.
