Ok,
try this, move your class to some place inside /src/client and implement
IsSerializable.
I hope this be enough to solve the problem.
import ContactInfo;
// ... imports ...
@PersistenceCapable
public class Employee *implements
com.google.gwt.user.client.rpc.IsSerializable*{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent
private ContactInfo myContactInfo;
// ... accessors ...
}
Best Regards,
Alessandro
