[resolvido] Vraptor - Redirecionamento para logic retorna IllegalArgumentException:

Assuntos Gerais
#1

Ao efetuar o redirect em meu controller para outro método da mesma classe conforme código abaixo retorna IllegalArgumentException (stacktrace completo no final).

[code]@Resource
public class DashboardController {

public void index() {
	[...]
}

public void changeProfile(int index) {
	[...]

	result.use(Results.logic()).redirectTo(DashboardController.class).index();
}

}[/code]

Analisando o código cheguei na classe DefaultLogicResult, onde no método abaixo tenta setar um proxy da classe.

private <T> void includeParametersInFlash(final Class<T> type, Method method, Object[] args) { Object params = creator.instanceWithParameters(DefaultResourceMethod.instanceFor(type, method), args); request.getSession().setAttribute(FLASH_PARAMETERS, params); }

É um possível bug do vraptor ou estou fazendo algo errado?

Ambiente:

  • vraptor rc1
  • glassfish v2

Olá,

Você fez isso direitinho… o problema é que o VRaptor coloca uma classe na Sessão que guarda os parâmetros
para o método que você está redirecionando, para suportar a passagem de parâmetros…
a gente não tinha testado isso no Glassfish… no Tomcat e no Jetty isso funciona sem problemas…

aparentemente o HttpSession do Glassfish só aceita atributos serializáveis, um pouco estranho…

Vamos verificar isso, e se possível corrigir até o proximo release (que já está chegando)

Lucas, obrigado.

Se você precisar de algum teste, por favor, envie-me MP. Estou migrando uma aplicação minha que utiliza atualmente vraptor2. Por enquanto tudo funcionando bem.

Há algum workaroud temporário enquanto sai o novo release?

Abraços

#4

Você está com o source do VRaptor3 aí né?

Pegue a classe:
br.com.caelum.vraptor.view.DefaultLogicResult

crie essa classe:

@Component
public class MeuLogicResult implements LogicResult {
   // conteúdo da DefaultLogicResult
}

remova o método includeParametersInFlash e todas as suas chamadas…

o vraptor vai usar agora essa sua classe ao invés da dele…
O efeito colateral de fazer isso, é que se você fizer:

result.use(logic()).redirectTo(ClientsController.class).view(client);

o parâmetro client não vai ser usado no redirecionamento…
