arrays - For loop in an $firebaseArray -

i found similar topics, of them outdated because i'm using angularfire 1.1.1.

i had angularjs app creating markers on google map. data stored in external json files , worked fine when turned arrays. when put data firebase database stopped working. ng directives data works fine, when accessing array data data in js code not work.

    app.controller('mapctrl', ['$scope', '$firebasearray', function($scope, $firebasearray){  var ref = new firebase("https://radiant-inferno-6439.firebaseio.com/tracks"); var syncobject = $firebasearray(ref);     ... 

with old offline json version logging syncobject looked this:

    [object, object, object]     0: object     1: object     2: object     length: 3     __proto__: array[0] 

but looks this:

    []     0: object     1: object     2: object     $$added: () { [native code] }     $$error: () { [native code] }     $$getkey: () { [native code] }     $$moved: () { [native code] }     $$notify: () { [native code] }     $$process: () { [native code] }     $$removed: () { [native code] }     $$updated: () { [native code] }     $add: () { [native code] }     $destroy: () { [native code] }     $getrecord: () { [native code] }     $indexfor: () { [native code] }     $keyat: () { [native code] }     $loaded: () { [native code] }     $ref: () { [native code] }     $remove: () { [native code] }     $save: () { [native code] }     $watch: () { [native code] }     length: 3     __proto__: array[0] 

why that? when print length of array says 0. tried $loaded function not affect.

    syncobject.$loaded().then(function(syncobject) {  console.log(syncobject.length);     }); 

neither can access properties of array, impossible loop through it.

looks $loaded() method isn't working. added 2 second timeout between loading data , doing else, started work.
