Problema com Richfaces 4 e panelMenu

E ai galera , blz

Eu estou tentando usar o exemplo do richfaces 4 do site da Jboss, o panelMenu, segue link abaixo:
http://richfaces-showcase.appspot.com/richfaces/component-sample.jsf?demo=panelMenu&skin=blueSky

Porém, está dando um erro na minha aplicação, ele exibe a seguinte mensagem na pagina xhtml

?The button/link/text component needs to have a Form in its ancestry. Please add <h:form>.

Já tentei mudar a localização do meu <h:form>, mas ainda sim continua dando a mensagem, onde q eu tenho q colocar isso no codigo?

menu.xhtml

    <h:form id="form">
        <h:panelGrid columns="2" columnClasses="cols,cols" width="400">
