title: Why the FlashVars have 1 empty element
body: <pre><code>            var images:Array = new Array();
              var flashVars:Object = stage.loaderInfo.parameters;
  
              for (var key:String in flashVars)
              {
                  var value:String = flashVars[key] as String;
                  images.push(value);
              }
              trace(images.length) // outputs 1
  </code></pre>
  
  <p>I am getting images urls from flashVars html, but i can't understand why there are an empty element, why this code outputs 1? if there are not flashVars passed to the application?</p>
