[resolvido] Vraptor - Redirecionamento para logic retorna IllegalArgumentException:

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

@Resource
public class DashboardController {

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

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

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

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

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…
