How do I make client side renderable object?

I'd like to write class which instances can exists only on client side and can render simple geometries from vertices.
I wrote it using this tutorial:
http://tdn.garagegames.com/wiki/Code/How_do_I_make_a_renderable_object%3F
and modified some lines and it works as I want, but instance of that class exists on server too.
So I found resource: http://www.garagegames.com/index.php?sec=mg&mod=resource&page=view&qid=6504
and modified lines in constructor:

mTypeMask |= StaticObjectType | StaticTSObjectType | StaticRenderedObjectType;
mNetFlags.clear(Ghostable | ScopeAlways);
mNetFlags.set(IsGhost);

to:

mTypeMask |= StaticObjectType | StaticTSObjectType | StaticRenderedObjectType;
mNetFlags.set(Ghostable);

and in onAdd method:

addToScene();

to:

gClientContainer.addObject(this);
gClientSceneGraph->addObjectToScene(this);

And now I suppose that object exist on client side, I can't see it rendered but I know that renderObject method is called. Has anyone know what is wrong?
