Before gwt 2.3 use autoBean, import com.google.gwt.autobean.shared,
and my autobean worked.

But in 2.4, this packege is removed, so import
com.google.web.bindery.autobean.shared, but the old code not work any
more,

Any one encountered this problem, and any suggestion.
Tks!

Hard to tell without an error message.

Did you think about changing the <inherits/> in your gwt.xml too?

This is usage:

BeanFactory:

public interface BeanFactory extends AutoBeanFactory {

AutoBean<IUser> user();

}

IUser:

public interface IUser extends Serializable {

public abstract Long getId();

public abstract void setId(Long id);

public abstract String getName();

public abstract void setName(String name);

}

toJson :

BeanFactory factory = GWT.<BeanFactory> create(BeanFactory.class);

IUser user = factory.user().as();

user.setId(0l);

user.setName("abc");

String userJson = AutoBeanCodex.encode(AutoBeanUtils.getAutoBean(user)).getPayload();

exception :
