Do Google Maps Flash API Markers fire an event when added to the stage?

With the Google Maps Flash API, I want to add an event listener which fires when the Marker is added to the Map using map.addOverlay();开发者_运维知识库 Event.ADDED_TO_STAGE is not fired, though it seems logical. What are the alternatives?

In case anyone ever wonders about this again and misses what I missed, the answer is to use a custom marker Sprite, and attach the ADDED_TO_STAGE listener to the sprite rather than the Marker.
