Just out of curiosity, why aren't you using flash remoting?

why not just use a webService, and then only show an error if something is
wrong.?

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

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?
