prototype

Suppose I have a page located at www.example.com/foo, and it contains an iframe with src="http://www.example.com/bar". I want to be able to fire an event from /bar and have it be heard by /foo. Using the Prototype library, I've tried doing the following without success:

Element.fire(parent, 'ns:frob');

When I do this, in ff 3.5, I get the following error:

Node cannot be used in a document other than the one in which it was created" code: "4 Line 0

Not sure if that's related to my problem. Is there some security mechanism that's preventing scripts in /bar from kicking off events in /foo?
