Hi there,
You'll want to probably do the equivalent of an AJAX call via Flex. I don't have it in front of me but I think you can use the HttpRequest object.
You'll basically have your object set up to retrieve the xml with a result handler on it. Whenever you need to call it, do so:
ActionScript Code:
myService.send();
and then you'll get your result via your handler:
ActionScript Code:
private function myResultHandler(event:ResultEvent):void
{
//do your handling stuff here....
}
obviously if you using things like ArrayCollections for drop downs and such, life will be a lot easier for you.
Hope that was at all helpful,
