Problema com <rich:panelMenu> e Ajax para atualização de painel

Tenho um layout padrão: menu, cabeçalho, rodapé e conteúdo. Estou utilizando Facelets/RichFaces e o componente panelMenu.
Quando eu clico no menu o painel não é atualizado. Vi um problema parecido e tentei utilizar a solução, mas não funciona.
Gostaria da ajuda de vocês para resolver o problema.

Segue os códigos:

menu.xhtml

public class menu {

private String corrente;

/** Creates a new instance of menu */
public menu() {
this.setCorrente("frmPadrao.xhtml");

/**

Pessoal, alguém tem um exemplo parecido ?
