Hey all,

I’ve got a problem… here’s an example script:

```auto

class Example {
		var xmlLoader;
		function Example (){
				this.xmlLoader = new XML();
				this.xmlLoader.onLoad = function(){
						wannaCallThis();
				}
		}
 
		function wannaCallThis(){
				trace('yay');
		}
 
		function loadTheXML(addy:String){
				xmlLoader.load(addy);
		}
}

```

Ok, so here’s the problem. What happens in the above, is that I call ‘loadTheXML()’, it loads the xml file into xmlLoader and then runs the event handler ‘onLoad’. My problem is here: once I get into the event handler ‘this’ refers to xmlLoader, not the class. Therefore, I have no way of calling wannaCallThis(). How do I call a member function of the class from inside the eventHandler?

Hope my question was clear. Thanks in advance!
