to GWTP

I use GWTP and restyGWT. I would like to use placeManager in restyGWT DispatcherCallback, when my rest server will answer with 401 unauthorised I would like to redirect application to login page, that User could apply credentials and retried his request.

To do this I have to somehow get instance of PlaceManager (from gwtp framework). I cannot use @Inject annotation, cause I have manuall call to constructor as follow:

public class ForbiddenDispatcherFilter implements DispatcherFilter {
    @Override
    public boolean filter(Method method, RequestBuilder builder) {
        builder.setCallback(new ForbiddenDispatcherCallback(method));
        return true;
    }
}


public class ForbiddenDispatcherCallback implements RequestCallback {
    protected RequestCallback requestCallback;

    public ForbiddenDispatcherCallback(Method method) {
        this.requestCallback = method.builder.getCallback();
    }

    @Override
    public void onResponseReceived(Request request, Response response) {
    if (response.getStatusCode() == Response.SC_FORBIDDEN || response.getStatusCode() == Response.SC_UNAUTHORIZED) {
        // make a hard redirect to login page
        // TODO change redirect to GWTP native
        Window.Location.assign("#login");
        // PlaceRequest placeRequest = new
        // PlaceRequest.Builder(placeManager.getCurrentPlaceRequest()).nameToken(Routing.Url.login).build();
        // placeManager.revealPlace(placeRequest);
    } else {
        requestCallback.onResponseReceived(request, response);
    }

}
