I don’t like adding event listeners to services. What if your reuse your service and don’t want other listeners…

better i think is this to attach a boolean to the TOKEN. check the boolean states before performing the work in your result handler.

var token:AsyncToken=_service.send();
token.executed=false;

in the result handler, first statements should be:
if (event.token.executed == false) {
event.token.executed=true;
//already fired (or firing);
return;
}

As a side note, make sure you remove your event listeners after the service has completed.

And Flex SDK 3.4.1.10084 fixes this issue so you can go back to the token best practice (which takes care of the tear down and removal of event handlers, etc).
