Hello all,
pre-apologize for my english.
I've a question about an AsyncCallback object passed to a gwt rpc
method with 'void' return type. If i have a rpc method where the
remote service interface, server-side and client-side implementation
looks like this:
public interface ApplicationService extends RemoteService{
public void method(int number);
}
public class ApplicationServiceImpl extends RemoteServiceServlet
implements ApplicationService {
public void method(int number){
//Do something
}
}
public interface ApplicationServiceAsync {
public void method(int number, AsyncCallback callback);
}
I don't need this callback because it will return anything. So can I
call this method passing 'null' like callback argument? I'm confused
about this and i would like to see your feedback.
