Hello Ben, Could you precise a little bit more what you want to do, and particularly what you ExternalInterface expect to achieve ? Because on any marker event, you have the marker in event.target so there is no issue to identify a marker. And for looking for a specific marker that would have a given user data (like a name) in a marker array, the method given by RIck is ok. What you can also use is an associative array in actionscript where the key is the marker and the value another object, if you do not wnat to subclass marker. Like :
aMarker=new Marker(latLng); myMarkersArray[aMarker] = myUserObject; and when you want to get the user object for a given marker in an event listener, you may do : theUserObject = myMarkersArray[event.target as Marker]; or you can do the opposite where the user object is the key and the markers are the value.
