Return value from ExternalInterface.call method

[prdv]

Hi people,
I can not achieve to get any return value from javascript other than
null.
In th HTML container I have a functions like this:

function f(p)
{
alert(p);
return(p);
}

In my flex app I call the browser function in the following way:

var ret:*;
ret = ExternalInterface.call( "f", "Hello" );
Alert.show( ret.toString() );

I get an alert in the browser saying "Hello" and another Alert from
flex saying "null".

What's wrong?... I think that I should get two alerts shown, no?

Hi,
I Finally found that the problem was related to the fact that the HTLM wrapper
did not have the <object> tag (it only had the <embed> tag)
I setup, both, the embed and object tags and now ExternalInterface.call
returns the right value under MSIE and FireFox.

Thanks a lot for your suggestions.
