[RESOLVIDO] Deseralizar Json + Vraptor + Extjs

Assuntos Gerais
#1

Boa noite. Estou desenvolvendo uma tela de consulta de parceiros, utilizando extjs. Estou mandando para a view, apenas informações em pacote, e a ordenação no servidor.
Só que na hora de o Vraptor atribuir valores para os parametros do controller, esta apresentando um erro, acredito eu na deserealização do json que vem com os dados da ordenação:

Método do Controller:

	@Path("parceiros/consultaparceiro.json")
	public void consultaParceiro(String argumento, int start, int page,
			int limit, List<Ordenacao> sort) {

Classe Ordenação

public class Ordenacao {

	private String property;
	private String direction;

Chamada ajax mada no Formdata no console do desenvolvedor aparece:

argumento:
page:1
start:0
limit:25
sort:[{"property":"id","direction":"ASC"}]
ajax_request:true

O Erro no vraptor:

pra funcionar assim os parâmetros deveriam ser:

"sort[0].property": "id",
"sort[0].direction":"ASC",

"sort[1].property": "name",
"sort[1].direction":"DESC",
...

Lucas, blz. vou ver se consigo fazer um override no envio das informações pelo Extjs.

Também estou com outro problema. coloquei a versão do vraptor vraptor-3.5.2-20130725.004258-7 do snapshot
e estou tentando utilizar Gson

e esta apresentando o seguinte erro:

o controller é este:

			this.usersLoggedIn.setEmpresa(this.emEnterpriseDao.getEnterprise(id)
					.getDatabase());
			result.use(json()).withoutRoot().from(new MessageExtjs("", true))
			.serialize();

e web.xml

Tem algum problema na utilização do Gson?

sobre esse cara:
The import br.com.caelum.vraptor.serialization.xstream.Serializee cannot be resolved

vc está com mais de um jar do VRaptor no classpath?

essa classe era package protected e ficou public na última versão.

Valeu Lucas, era isto mesmo…
ficou uma referência a uma versão antiga no classpath
Obrigado
