Actually, I spoke too soon, the latest version of PrettyFaces now lets

And it also handles the form-less GET actions.

One of the many reasons I shy away from using Managed Beans in my own projects (too much work to mange all that "free" management they give you ;) ).

Are you using client-side state saving? Maybe in this case, during restore view, it needs to look up something in the bean which has the @PostConstruct?
