George -
I figured maybe the way you were passing params was incorrect and thus
causing the fault event that you are catching. I don't use ColdFusion,
I use Java Servlets on the back end. But, should be very similar. I
get the fault event only when the servlet cannot be called at all. I
use result codes, error messages, embedded in my application XML
returned from the back end to indicate application error information.
So... from my experience, I would guess that your fault event that you
are catching indicates that your back end is not getting called
correctly. Have you put a debugger or tracing in your cfm file and
verified that it is actually getting called successfully?

Hi Scott,
I have been through many Flex Tutorials but unfortunately our world
lacks of tutorials for connectivity with ColdFusion. I am an
experianced CF developer but unfortunately I cannot figure out how to
proceed with data through Flex and CF.
Indeed - your way is much easier to write and better to understand
than the one that I have posted. I will keep that one :-) Thanks!
But still... the 'fault' function in the HTTPService tag is always
triggered! Even with your own way.
How can I handle this? All I want is to be able to 'alert' the users
that there is some kind of error (I know how to get the exact error
message through the event handler) but I have no clue how to trigger
this function if and only if there is some kind of problem in my CFM
file.
any ideas?
Thanks,
George

I have not seen this syntax for passing request params to an
HTTPService. Of course that doesn't mean it is wrong :) But,
here is how I would do it.
Change button definition to
<mx:Button label="Add Employee" click="callServer()"/>
then
public function callServer():void
{
var params:Object = new Object();
params.firstName = firstName.text;
...
srv.send(params);
}

Hi,
I have this code. It works perfect but I would like to get
alerted only when I have some kind of error in my test.cfm file.
Instead, the 'errorAlert()' function always is triggered :(
Any idea's on how to make this work only when I have problems in
my test.cfm file?
