timer problem

[genesistr]

Hi,

I have timer class and some classes use timer.
but when i come back from timer with callback function, i can see this. properties.

function Timer(dName, dCallback){
     this.timer = null;
     this.name = dName;
     this.isRunning = false;
     this.interval = 50;
     this.callback = dCallback;
 }
  
Timer.prototype.Start = function()
 {
     this.timer = self.setTimeout(this.callback,this.interval);
     this.isRunning = true;
 }

var timer;
function File(path) 
{
    ....
    if (timer == null) 
        timer = new Timer("load",File.prototype.WaitForUnFinishedFiles);
    ....
}
  
File.prototype.WaitForUnFinishedFiles = function()
 {
    var isAllFinished = true;
    for(eFile in cache)
    {
        if(!cache[eFile].isReady)
         {
            isAllFinished = false;
            break;
        }
    }
     debugtext("load :::" + this.fileName);
     if(!isAllFinished)
         timer.Start();
 }

and i call it in main.js

file = new File("http://bytes.com/images/simon_00.png");
file.WaitForUnFinishedF();

i used debugtext just for testing something but it says undefined. and its important for me to see this. properties after coming back from timer.

thanks
