New 'Worker' framework - restarting a service?

Question

Hey Guys,
Does anyone know how to restart a Service using the new background threading framework. The teaser out there at the moment indicates this is intended but I can't make it work.
Here's my service:
private class LoginService extends Service<User>
    // leaving out the get/sets for brevity
    public final StringProperty userNameProp = new StringProperty();
    public final StringProperty passwordProp = new StringProperty();
    protected Task<User> createTask()
        final String userName = userNameProp.get();
        final String password = passwordProp.get();
        return new Task<User>()
            protected User call() throws Exception
                return // do remote service login with userName and password
} And this is the code using it:
public class LoginController
    private LoginService loginService;
    public LoginController()
        loginService = new LoginService();
        loginService.stateProperty().addListener(new ChangeListener<Worker.State>()
            public void changed(ObservableValue<? extends Worker.State> source, Worker.State oldState, Worker.State newState)
                if (newState.equals(Worker.State.SUCCEEDED))
                    // show application main view
    public void doLogin(String userName, String password)
        loginService.userNameProp.set(userName);
        loginService.passwordProp.set(password);
        loginService.start();
        // I've tried restart(), cancel(), reset() and using various if !state().equals(State.READY) checks before calling each, etc
}Any hints or tips appreciated. Hopefully the docco will be more detailed before long, but until then I'll take whatever works!

Sorry, actually restart() does now seem to work as expected. I must have had something else in my code causing the issue earlier (not sure what) that seems to have resolved itself.
