Problems with Flash / JavaScript Integration kit

We have been experimenting with the Flash / JavaScript Integration Kit. In overall it is a fairly decent implementation, but we ran into several issues with it:

• The page that describes how to invoke an ActionScript function from JavaScript shows the following example:
  var tag = new FlashTag('flashContent.swf',300,300,'7,0,14,0');
  // the addFlashVar cannot be found
  tag.addFlashVar('lcId', uid);
  tag.setId('myFlashContent');
  tag.write(document);
  
  The problem is that the addFlasVar function is not even available in the FlashTag class. Neither is the 'version' argument of the constructor. The proper way to register the lcId variable is:
  
  tag.setFlashvars( "lcId=" + uid );
  
  
• The way the kit invokes ActionScript functions is by loading the 'gateway' flash movie and passing a query string with the name of the function and all encoded arguments in the flashvars. The problem with that approach, of course, is if JavaScript makes subsequent ActionScript calls back-to-back, only the last one is executed. It is similar to the issue #6 in the list of Known Issues. The root cause of the problem is FlashProxy.js:
  
  if(!document.getElementById(divName))
  {
  var newTarget = document.createElement("div");
  newTarget.id = divName;
  document.body.appendChild(newTarget);
  }
  // multiple consecutive calls will be modifying the same DIV
  var target = document.getElementById(divName);
  var ft = new FlashTag(this.proxySwfName, 1, 1);
  ft.setVersion('6,0,65,0');
  ft.setFlashvars(qs);
  target.innerHTML = ft.toString();
  
  One possible workaround is to push JS-to-AS invocations onto a stack and have a timer that checks the stack and then invokes all the functions on from it one by one. If someone has a simpler solution, please let us know.
