I need to show multiple routes on a map. In other words, I need to call loadFromWaypoints() a number of times instead of just once, so that the requests overlap. The event handlers will be called some time after, and in these event handlers I have no reference back to the original request.
The waypoints that I pass to the loadFromWaypoints call are generated from a section of XML. In this event handler, I need to have a label of some sort that I can use to find out which section of the source XML the directions are derived from. But I can find no way to add a label or some identifier to the Directions class. I have tried deriving from the Directions class and adding properties but none of these work. It seems that the loadFromWaypoints() function is inherently stateful, i.e. it relies on state being held elsewhere so that you know the context of the request when the DirectionsEvent handler is called. But this seems to go against the architecture of the rest of Flex in that the Event object passed to the event listener function usually tells you what generated the event in the first place in the target and currentTarget properties. DirectionsEvent doesn't seem to support anything like this. I think that either the Directions class should have a metadata property of some sort, for example "id", or there should be a parameter in the loadFromWaypoints call to allow me to enter an id string, that will be returned in the DirectionsEvent. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API For Flash" group.
