Route with store.findAll not working correctly if records of that type already present from previous page

[adam-knights]

Originally posted against Ember emberjs/ember.js#12488.

This was working fine with Ember 1.13.10 and Ember Data 1.13.12, doesn't seem to work with Ember 2.1.0 and Ember data 2.1.0.

If I navigate to http://localhost:4200/orders then it works fine and I see 6 orders come in from the api and the page displays information on all seven orders.

If I first navigate to http://localhost:4200/members/1234/orders, then I correctly see 3 orders from that member account. However, if I now press the link to goto http://localhost:4200/orders it only displays the same 3 orders. The api is deffinitely hit again and it correctly returns 6 orders.

I put a breakpoint at the end of Ember Data's _findAll method and its returning an array with 6 items from the return store.peekAll(modelName); line. Where else could things be going wrong? (More than happy to debug myself)

This is my orders route:

import Ember from 'ember';
import AuthenticatedRouteMixin from 'ember-simple-auth/mixins/authenticated-route-mixin';

export default Ember.Route.extend(AuthenticatedRouteMixin, {
  model: function() {
    return this.store.findAll('order').then(function(orders) {
      return orders.sortBy('creationDate').reverse();
    });
  },
  afterModel: function(orders) {
    document.title = 'Orders';
    return Ember.RSVP.all(orders.getEach('orderItems'));
  }
});

This is my account (member) model:

import DS from 'ember-data';

export default DS.Model.extend({
  accountType: DS.hasMany('accountType', {async: true}),
  addresses: DS.hasMany('address', {async: true}),
  contacts: DS.hasMany('contact', {async: true}),
  membershipType: DS.belongsTo('membershipType', {async: true}),
  communicationsAvailable: function() {
    var commsAvailable = [];
    this.get('contacts').forEach(contact => commsAvailable.push.apply(commsAvailable, contact.get('communicationsAvailable')));

    return commsAvailable.filter(function(value, index, ca) {
      return ca.indexOf(value) === index;
    });
  }.property('contacts.@each.communicationsAvailable'),
  joinDate: DS.attr('date'),
  name: DS.attr('string'),
  orders: DS.hasMany('order', {async: true}),
  prices: DS.hasMany('price', {async: true}),
  supplierCode: DS.attr('string')
});

This is my order model:

import DS from 'ember-data';

export default DS.Model.extend({
  account: DS.belongsTo('account', {async: true}),
  address: DS.belongsTo('address', {async: true}),
  collect: DS.attr('boolean'),
  deliveryDate: DS.attr('date'),
  paymentDate: DS.attr('date'),
  memberPurchaseOrderNumber: DS.attr('string'),
  orderItems: DS.hasMany('orderItem', {async: true}),
  orderNotes: DS.hasMany('orderNotes', {async: true}),
  orderNotifications: DS.hasMany('orderNotifications', {async: true}),
  orderStatus: DS.belongsTo('orderStatus', {async: true}),
  creationDate: DS.attr('date')
});

Stefan now thinks this might be an ember issue. I'll close here for now and reopen if required.
