For when Angular is dumb and doesn't allow filtering of object maps.

objectToArray.js

$scope.objectToArray = (function() {
    function convert(object) {
        var keys = Object.keys(object);
        var array = [];
        keys.forEach(function(i) {
            array.push(object[i]);
        });
        return array;
    }
    return function(object) {
        return (convert(object));
    }
})();
