Yahoo! doesn't have a Flex 2.0 map API, so if we want to have a map, we need to use the Flash API. But having the map in Flash and the rest of the app in Flex it is not as simple as having everything written in Flex. This is because now the player has 2 virtual machines, one for Flex that runs ActionScript 3 and another for Flash that runs ActionScript 2.
