Hey David,
I loaded the demo, the problem is coming from the custom icons:
[Embed(source="../../images/blue-dot.png")] private var
blueIcon:Class;
[Embed(source="../../images/green-dot.png")] private var
greenIcon:Class;
Since neither of these two images exist, when the code tries to
instantiate the class, it fails. A constructor is a primary function
of a class. To fix the bug use this:
public function createMarker(latlng:LatLng, name:String,
address:String, type:String): Marker {
var marker:Marker = new Marker(latlng, new MarkerOptions
({iconOffset: new Point(-16, -32)}));
var html:String = "<b>" + name + "</b> <br/>" + address;
marker.addEventListener(MapMouseEvent.CLICK, function
(e:MapMouseEvent):void {
marker.openInfoWindow(new InfoWindowOptions
({contentHTML:html}));
});
return marker;
}
