You can always check out the angular change log

https://docs.angularjs.org/guide/migration#migrating-from-1-2-to-1-3

Found out that the problem is that the data is an associative array like so:

var some_data = {"id_x": {some object}, "id_y": {some other object}};

Instead of just:

var some_data = [{some object}, {some other object}]

case closed !
