RE: [flexcoders] HTTPService Error event

[Tracy Spratt]

Your call is an update call, but is it returning someithig to Flex
anyway? On all HTTPService calls, I have the backend wrap my data in a
status node, and for update calls, I just return the empty status node
with status="sucess".  This lets me tell the user when the update
happens successfully, or navigate somewhere else, or do whatever I want.

 

If you are not retuning anything, perhaps Flex sees this as a fault.

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?
