OK... I figured out that is was a "setPath(myArray)" vs "set('path',
myArray)" BUG in google.maps.Polyline.
Even though Polyline is a MVCObject and it doesn't have a real 'path'
property... because "google.maps.Polyline.prototype.setPath ()"
doesn't call 'google.maps.MVCObject.set('path', myArray)'. So my
"google.maps.event.addListener(poly, 'path_changed', function()
{ ...}" get triggered.
My kluge (poor fix) is to add
google.maps.event.addListener(poly, 'path_changed', function() {
alert("FIX: set('path', value) and setPath(value) has
changed.");
// poly.setPath(poly.get('path'));
});
poly.set('path',path1);
It is a poor fix because the polyline can get really big.... and two
copies makes it worst.
A better fix would be to manually trigger an event.
