#1

Bom dia.
Estou com um problema na utilização do VRaptor + GSon + extjs:

Web.xml

   <context-param>
    <param-name>br.com.caelum.vraptor.packages</param-name>
    <param-value>
    	br.com.caelum.vraptor.util.extjs,
        br.com.caelum.vraptor.deserialization.gson,
        br.com.caelum.vraptor.serialization.gson    	
    </param-value>
  </context-param>

Controller

	@Path("catalogs/users/update")
	@Consumes("application/json")
	public void updateUsers(Users user) {...}

Estranho como esta mandando o json:
