I am doing something wrong here trying to convert pixels to lat lng

	var bbox = bounds.toArray();
	var p1 = map.getLonLatFromPixel(bbox[0]);
	var str  = "Lat: " + p1.lat + " (Pixel.x:" + p1.x + ") Lon: " + p1.lon + " (Pixel.y:" + p1.y + ")\n";
	alert(str);

produces the following alert

	Lat: NaN (Pixel.x:undefined) Lon: NaN (Pixel.y:undefined)
