Исключение сериализации с помощью GXT RPCMAP

Я возглавляю следующий выпуск

При загрузке List<InfoClasifCustom> в сеанс.

Этот класс следующий:

public class InfoClasifCustom extends BaseModelData implements Serializable, IsSerializable, BeanModelTag, Comparable<InfoClasifCustom>{



private String idClasificacion;

private String color;

private Integer numEquiposGrupo;

private Long idGrupo;



private Boolean isEditable=false;

private static final long serialVersionUID = 8202856915683008011L;



public InfoClasificacionCustom() {



}



public void setColor(String color) {

    this.color = color;

}



public Integer getNumOrden() {

    return get("numOrden");

}



public void setNumOrden(Integer numOrden) {

    set("numOrden",numOrden);

}

Поэтому я использую как стандартные атрибуты, так и RPCMap BaseModelData для атрибутов этого класса, и все они являются примитивными типами или оболочками (thats, int или Integer).

Может ли быть проблема сериализации RPCMap? Может быть, список? У меня только этот вопрос на производстве, так как это Tomcat-кластер.

Любой мог бы помочь?

Проблема связана с реализацией RpcMap. К сожалению, RpcMap не реализует сериализацию (в старом выпуске GXT). Чтобы устранить проблему, я предлагаю добавить в свой проект класс " com.в ExtJS.специалисты GXT.пользовательский интерфейс.клиент.данные.RpcMap", то есть равняется реальному GXT "RpcMap", но реализует сериализуемый. Таким образом компилятор использует ваш класс.

Ниже приведен пример кода:

/**  * RpcMap is used to workaround a part of GWT RPC system.  *   *
<p /> The GWT RPC rebinder generates field serializers for every type
that is  * assignable to any type in the RPC interfaces.  *   * <p />
If BaseModel was to use "Map&lt;String, Serializable> map" this would
trigger  * the RPC system to generate field serializers for EVERY
Serializable type in  * your GWT Module's class path.  *   * <p />
Therefore BaseModel uses "Map&lt;String, RpcField> map" and relies on
type  * erasure (cast to Map&lt;Object,Object>) to work around this. 
*   * <p /> The only drawback is that if you have to ensure that field serializers are  * generated for any type you add to this map 
*   * <p /> RpcMap ensures that the following types are supported Byte, Short, Integer,  * Long, Float, Double, Date, Boolean, and
arrays of these types. As well as  * List, Set and Map  */
