Problem invoking web service

Question

We have a web service that is working some times and not
others. It is local so it's not a problem with the internet being
busy or anything like that. We do
service.addEventListener(InvokeEvent.INVOKE, debugInvoke);
service.send();
and the times when it fails, debugInvoke (a local function)
never gets called. We also have event handlers for RESULT and FAULT
and those two don't get called either.
The doc says
"The invoke event is dispatched when a service Operation is
invoked so long as an Error is not thrown before the Channel
attempts to send the message" but I don't really know what that
means. Can anybody shed some light on this? Thanks.

I don't know if you're having the same problem, but when I
was having timing issues, it was related to my calling of the web
service before the WSDL was fully loaded.
In my case, the service was being called when my app
initialized. My solution was to add a load handler to my service
like so:
service.addEventListener(LoadEvent.LOAD, loadWsdlHandler);
service.loadWSDL();
My loadWsdlHandler method then made the actual service call,
secure in the knowledge that the WSDL was fully loaded.
The WSDL only needs to be loaded once before the first
service call. If your service is first called by user interaction,
then you could add the component in a disabled state, load the WSDL
when the app initializes, and your load handler can enable the
relevant control.
