This looks good to me.

With FireBug, I've verified that a POST request is indeed executed when I change the zoom level, and it appears that everything is in order:

And the request payload looks right - seems like all of the necessary information is present.  (Though, man, those auto-generated client ids sure are huge!)

I get a response back that looks like this:

  <?xml version="1.0" encoding="utf-8"?>
  <partial-response><changes><update id="javax.faces.ViewState"><![CDATA[1747337848471748955:2683565346534242854
  ]]></update></changes></partial-response>

However, with f:ajax, my value change listener is never invoked on the server, so the menu doesn't update, even though I've specified that the menu should go through the execute phase of the lifecycle.

Does anyone know why my value change listener is not invoked? Am I doing something wrong, or is this a bug?

Seems like the execute portion of the lifecycle is not being invoked properly.  I don't see anything wrong in your code - so I suspect there is a bug here.
