With my own testing, it appears that getMetadata only returns an
object after the layer has finished rendering. Intuitively this makes
sense. However the problem is there isn't an event directly designed
to tell you when this is ready. I was able to use the tilesloaded
event on the map to accomplish the same thing though.
map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
ctaLayer = new google.maps.KmlLayer('http://gmaps-
samples.googlecode.com/svn/trunk/ggeoxml/cta.kml');
google.maps.event.addListenerOnce(map, 'tilesloaded', function()
{ console.log(ctaLayer.getMetadata()) });
ctaLayer.setMap(map);
