Firefox/Netscape Applescript Dictionary register command

Hi all,
Anyone use the “register” command in the Applescript Dictionary entry for the Firefox/Netscape browsers ?

Specifically, the “Spyglass entry” in the AS dictionary is:

Spyglass:

OpenURL: Load a URL

OpenURL  string 

– URL to load

register URL echo: Register a URL echo handler. The handler will get called whenever a new URL is loaded

register URL echo  type class

– signature of listener

unregister URL echo: Cancels URL echo

unregister URL echo  type class

– signature of listener

The OpenURL command works fine. I can’t seem to get the register command to work. Anybody have an example?

Note: I am using AS 1.9.1 on Mac OSX 10.2.8 and ScriptEditor 2.0 (beta version).

Any thoughts would be greatly appreciated!

Thanks,

Ed Mansky

What happens when you call the command? What does your listener look like? Does the ae type/class match up?
