Problema Primefaces + JSF

Olá pessoal, estou com um problema numa aplicação que estou desenvolvendo usando JSF e Primefaces, Quando chamo minha pagina pelo botão, ela não consegue redirecionar,
a pagina principal quando tem o botão clickado, passa para a nova pagina, mostra o novo caminho porem mostra a seguinte mensagem:
