ExternalInterface.addCallback does not work right

Question

I have js code:

function onFlashReady() {        
    sendToAS("sit");
}

function callJS(value) {        
    onFlashReady();
    return "Hi Flash.";
}

function thisMovie(movieName) {
     if (navigator.appName.indexOf("Microsoft") != -1) {
         return window[movieName];
     } else {
         return document[movieName];
     }
 }
 function sendToAS(value) {         
     thisMovie("FlashID").callAS(value);
 }

html:

    <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="850" Height="588" id="FlashID" tabindex="0">
      <param name="movie" value="BusFlex/BusProducts.swf" />
      <param name="quality" value="high" />
      <param name="wmode" value="opaque" />
      <param name="allowScriptAccess" value="always" />
      <param name="swfversion" value="6.0.65.0" />
      <param name="expressinstall" value="Scripts/expressInstall.swf" />
      <!--[if !IE]>-->
         <object type="application/x-shockwave-flash" data="BusFlex/BusProducts.swf" width="850" height="588">
      <!--<![endif]-->
      <param name="quality" value="high" />
      <param name="wmode" value="opaque" />
      <param name="allowScriptAccess" value="always" />
      <param name="swfversion" value="6.0.65.0" />
      <param name="expressinstall" value="Scripts/expressInstall.swf" />
      <div>
         <h4>Установите или включите Adobe Flash Player.</h4>

      </div>

         </object>
      <!--<![endif]-->
      </object>
      <script src="Scripts/swfobject_modified.js" type="text/javascript"></script>
      <script type="text/javascript">
      <!-- swfobject.registerObject("FlashID"); //-->
      </script>
      </div>

and actionscript code:

protected function application1_creationCompleteHandler(event:FlexEvent):void
{
     flash.system.Security.allowDomain("http://mysite.ru");
     flash.system.Security.allowDomain("http://localhost");
     if(ExternalInterface.available)  
     {
          ExternalInterface.addCallback("callAS", fromJS);
     }
     ExternalInterface.call("callJS", "Hello JS!");
}
public function fromJS(str:String):void 
{
   ...
}

But it works in IE only. In FF this does not work. Help me please.

Answer 1

It looks like the issue is in your flash embed html, Mozilla browsers rely on the embed tag but you have object again. Try using something like so within your object node:

<embed type="application/x-shockwave-flash" data="BusFlex/BusProducts.swf" width="850" height="588" allowscriptaccess="always">
</embed>

    <param name="movie" value="BusFlex/BusProducts.swf" />
    <param name="quality" value="high" />
    <param name="wmode" value="opaque" />
    <param name="allowScriptAccess" value="always" />
    <param name="swfversion" value="6.0.65.0" />
    <param name="expressinstall" value="Scripts/expressInstall.swf" />
