Consulting the specification for f:event (http://java.sun.com/javaee/javaserverfaces/2.0/docs/pdldocs/facelets/f/event.html), I find that the signature is required to match public void listener(javax.faces.event.ComponentSystemEvent event) throws javax.faces.event.AbortProcessingException.
That's actually too bad. When I do a preRenderView event with viewParams, I don't need the CSE parameter, and I'd rather not couple my managed bean with the JSF API. So, it sure would be nice if I had the flexibility of using the signature public void listener() instead. Mojarra actually lets me do that!
I'm almost certain that we agreed that the event parameter (and exception signature) were optional. I clearly remember having that discussion. I don't have it in my archives, but for those that have them, the discussion should start around Jan 17, 2009.
Thus, I consider this a spec error. The fact that Mojarra implements the desired behavior is a partial indication that we agreed on it, too.
