I am using two java applets in my web page (let's call them XMLPlugin and DSigner).

I create Java object by calling XMLPlugin applet's method "createObject(<params>)":

var myObj = XMLPlugin.createObject(<params>);

Method createObject returns object of type <my_type>.

I want to send myObj to the other applet DSigner:

DSigner.addObject(myObj);

I get following exception in Java:uncaught exception: java.lang.ClassCastException: sun.plugin2.main.client.MessagePassingJSObject cannot be cast to <my_type>. Problem is, I am getting object of type MessagePassingJSObject instead of <my_type> returned by createObject() method.

Strange is that Firebug shows correct type <my_type> for variable myObj before entering the method DSigner.addObject(myObj).


I am also getting correct objects using other browsers (Internet explorer, Chrome).


Thank you, any help would be really appreciated.
