List com array no Json

Front-end
#1

Olá, alguém poderia me ajudar…

public void xxx(String name) {  
        Plan plan = planDAO.listName(name, Currency.EUR);  
      
        //System.out.println(">>>>>>>>>>>>>: "+plan.getPrices());  
                   //>>>>>>>>>>>>>: [Price [id=24, price=395.0, currency=EUR], Price [id=25, price=510.0, currency=USD], Price [id=26, price=1066.0, currency=BRL]]  
      
        result.use(json()).from(plan, "XXXX")  
        .serialize();  
    }

Da forma que esta retornando json, não estou conseguindo pegar os valores da parte do Price na posição 0 no javascript.

Os dados do Price, não estão sem enviado pelo browser.

    //var cartasiPlan_price = json.XXXX.prices[0].price;

tente colocar um .recursive() antes do .serialize()… se não funcionar dê include(“prices”)

Obrigado pela resposta, mas resolvi de outra forma…

result.use(json()).from(plan, "XXXX").include("prices").serialize();

mas tive que criar

package com.siter.site.infra;

import java.util.Collection;

import javax.servlet.http.HttpServletResponse;

import br.com.caelum.vraptor.interceptor.TypeNameExtractor;
import br.com.caelum.vraptor.ioc.Component;
import br.com.caelum.vraptor.serialization.ProxyInitializer;
import br.com.caelum.vraptor.serialization.xstream.XStreamJSONSerialization;

import com.thoughtworks.xstream.XStream;
import com.thoughtworks.xstream.converters.collections.CollectionConverter;

@Component
public class CustomJSONSerialization extends XStreamJSONSerialization {

  public CustomJSONSerialization(HttpServletResponse response, TypeNameExtractor extractor, ProxyInitializer initializer) {
    super(response, extractor, initializer);
  }

  @Override
  protected XStream getXStream() {
    XStream xstream = super.getXStream();

    xstream.registerConverter(new CollectionConverter(xstream.getMapper()) {
      @Override
      @SuppressWarnings("rawtypes")
      public boolean canConvert(Class type) {
        return Collection.class.isAssignableFrom(type);
      }
    });

    return xstream;
  }

}
