Objects load in different position each time I refresh the page - Three.js - OBJMTLloader

Question

I load some objects in my scene:

var objectInfo = [
{"objURL":"3D/Barrel/barrel.obj", "mtlURL":"3D/Barrel/barrel.mtl","xPOS":0,"yPOS":-2,"zPOS":-260,"xROT":0,"yROT":0,"zROT":0,"scaleX":0.6,"scaleY":0.6,"scaleZ":0.6},
{"objURL":"3D/Sofa/sofa.obj", "mtlURL":"3D/Sofa/sofa.mtl","xPOS":0,"yPOS":0,"zPOS":0,"xROT":0,"yROT":4,"zROT":0,"scaleX":1,"scaleY":1,"scaleZ":1},
{"objURL":"3D/Lamp/lamp.obj", "mtlURL":"3D/Lamp/lamp.mtl","xPOS":210,"yPOS":-20,"zPOS":10,"xROT":0,"yROT":50,"zROT":0,"scaleX":1,"scaleY":1,"scaleZ":1},
];

for (var i = 0; i < objectInfo.length; i++) {

                      loader=new THREE.OBJMTLLoader();

                      loader.addEventListener('load', function (event) { //callback f. to load .obj and .mtl

                          obj = event.content;

                          var c=count(); //just an external counter because i is not defined in here

                          obj.position.set(objectInfo[c].xPOS,objectInfo[c].yPOS,objectInfo[c].zPOS);
                          obj.rotation.x=objectInfo[c].xROT;
                          obj.rotation.y=objectInfo[c].yROT; 
                          obj.rotation.z=objectInfo[c].zROT;

                          obj.scale.set(objectInfo[c].scaleX, objectInfo[c].scaleY, objectInfo[c].scaleZ);

                          scene.add(obj);

                          OBJS[c]=obj; 

                      });

                      loader.load(objectInfo[i].objURL,objectInfo[i].mtlURL);

 }

But when I hard refresh the page (F5, Chrome) without having changed anything , the objects are in different position than before. When I hit again the F5, the objects are in their old position. ANd this happens alla the time and it is random where the objects will be.

What is the problem? Please answer because I have made much research before posting.

EDIT: alternative implementation without counter() : (still not working)

  for (var i = 0; i < objectInfo.length; i++) {

                      loader=new THREE.OBJMTLLoader();

                      loader.addEventListener('load', function (event) { //callbac f. to load .obj and .mtl

                          obj = event.content;                      

                          var objectInfo2=objectInfo.pop();

                          obj.position.set(objectInfo2.xPOS,objectInfo2.yPOS,objectInfo2.zPOS);
                          obj.rotation.x=objectInfo2.xROT;
                          obj.rotation.y=objectInfo2.yROT; 
                          obj.rotation.z=objectInfo2.zROT;

                          obj.scale.set(objectInfo2.scaleX, objectInfo2.scaleY, objectInfo2.scaleZ);

                          scene.add(obj);

                          // OBJS[c]=obj; 

                      });

                      loader.load(objectInfo[i].objURL,objectInfo[i].mtlURL);

    }

Also, not only the position attributes are randomly changed but also scale etc.

Answer 1

load events will fire in the random order.

--edit--

I think the problem is related to the counter function call because it assumes that the first call is from the first(in the array) object load event callback.

OBJMTLLoader has load: function ( url, mtlurl, onLoad, onProgress, onError )

you can pass onLoad with the right index.
