Why my Backbone collection fetch returns only one item

Step by steps

- Use Fildder to inspect network traffic, make sure of what is returned by the server has multiple objects.

- Make sure that your IDs are unique

- If you override the base model idAttribute, make sure that all items have a distinct attribute for the one marked as the ID by idAttribute. In the following example, if two item had the same name, only one of them would show up :

Export.Model = Backbone.Model.extend(
{
  urlRoot: "/apis/destinations",
  selected: false,
  idAttribute: "name",
  (...)
