Olá!
Gostaria de fazer uma pagina que tivesse um menu que ao clicar em uma opção carregasse outra pagina em um include, sendo que, eu tentei fazer de uma maneira que nao deu certo:

  • Coloquei em cada opção do menu um commandlink com um parametro em cada um, e o valor desse parametro seria o nome da pagina a ser carregada ao clicar.
  • Acrescentei um bean somente para receber esse valor em um atributo
  • coloquei um a4j:include, referindo-se ao atributo.

Quando vou executar o projeto ele dá um erro estranho.

Alguém teria um exemplo de como fazer isso???

To mandando um projeto que fiz para testar:

Pagina principal:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>

</table>	
</f:view>

</html>

Pagina a ser chamada:

	public void setPagina(String pagina) {

E esse erro se repete mais umas 6x…

Mal acabei de postar e resolvi…

Foi resolvido com a inicialização do atributo no bean com uma pagina default:

private String pagina = "branco.jsp";

Vlwz!!!

Realmente pimenta em seu jsp vc estava chamando uma ação pagina que não tinha nenhum valor.

resolveu totalmente seu problema?!

qualquer coisa posta ai novamente!

:wink:

pimentaft

A principio resolvei sim, foi uma maneira que achei de usar o include em um menu grande. Não sei se é o mais viavel.
Eu criei um jsp vazio para inicializar a pagina no bean.Em cada menu eu coloquei um parametro.
O erro é porque o include nao inicializava com nada.
Obrigado pela moral!
