Refreshing Google Maps API V3 Layers

Question

I\'ve been having trouble getting Google Maps API v3 to update correctly. I\'ve got a javascript timer running that should be refreshing the traffic layer periodic

I haven't work with traffic layers yet, so I'm not sure if this will work for you. I read the setZoom(getZoom()) trick but when I need to refresh the tiles (the classic one. The map itself) it didn't work either. I need to show/hide a grid in Gmaps (without reloading the page)

After searching and testing I got it working with these three lines:

        google.maps.event.trigger(map, 'resize'); // Can't remember if really helps
        map.setZoom( map.getZoom() -1 );    
        map.setZoom( map.getZoom() +1 ); // It won't flicker or make the transition between zoom levels. GMap just ignore the zoom change but redraw the tiles :/

I repeat. I don't know if this works with traffic layers but test it anyways. It kept me awake 2 days.
