The same behaviour occurs with polygons. To deal with this (personnaly
I prefer both events being fired) I put all the addListeners and
removeListeners in two functions in the map and deactivate/activate
the map listeners calling them from on ROLL_OVER or ROLL_OUT event
handlers in the polygon :
function addMapMouseListeners():void {
map.addEventListener(MapMouseEvent.MOUSE_DOWN,onMapMouseDown);
map.addEventListener(MapMouseEvent.MOUSE_UP,onMapMouseUp);
}
function removeMapMouseListeners():void {
map.removeEventListener(MapMouseEvent.MOUSE_DOWN,onMapMouseDown);
map.removeEventListener(MapMouseEvent.MOUSE_UP,onMapMouseUp);
}
