[flexcoders] Webservice not invoking???

[Chris Doherty]

I have a module that employs a web service to get data from a cold
fusion component.  I make the request of the web service, but the web
service never fires the invoke event and the data is never retreived.
 Any suggestions?  Any help is very much appreciated.

Thanks,
Chris
