I think I understand, but would love to see an example if you have one. So far I'm really digging working with Flex.

Send() returns an AsyncToken, which is a dynamic object that is associated with the specific send call, to which you can add any properties that you want. You can include functions if you want, but I usually just send a couple string parameters, on that indicates an id for the call, and an optional one that indicates special processing. In the result handler, you can access the AsyncToken using event.token, then access the values stored in you properties. I use a switch statement to determine what to do with any given result. So all results are in one place. It makes it easy to chain calls, and to maintain that chain. If you are interested, I can post some sample code.

You only have it on callID, not callStatus. -Andy On 4/23/08, Steve Good <[EMAIL PROTECTED] <mailto:sgood%40lanctr.com> > wrote: > (I sent this earlier, but it never made it through, so I apologize if it > ends up being a double post) > > > > I'm trying to make a call to a remote script at regular intervals.
