Formulário não limpa qdo vota ao menu

dlsilva1812 · Julho 13, 2012, 6:24am

Bom dia galera sangue bom.

É o seguinte, tenho na minha aplicação uma rotina de pesquisa, até aí td bem, efetuo a busca, me trás o retorno, eu clico neste retorno, abre o formulário com os campos preechidos, se acaso eu clicar no link do menu que se encontra no cabeçaho da tela, e retorno para o cadastro o formulário continua preenchido, como faço para limpar estes dados qdo eu saio da tela?

Meu faces-config.xml está assim.
