DEVELOPING COLDFUSION 9 APPLICATIONS
Flex and AIR Integration in ColdFusion
The second tag in this example fails because it tries to divide by zero (0)
cfset
tag describes the error; ColdFusion returns this attribute to the SWF application.
To handle the error in your SWF application, create a fault handler like
import mx.remoting.*;
import mx.services.Log;
import mx.rpc.*;
// Connect to service and create service object
var CFMService:Service = new Service(
"http://localhost/flashservices/gateway",
null,
"helloExamples",
null,
null );
// Call the service causeError() method
var pc:PendingCall = CFMService.causeError();
// Tell the service what methods handle result and fault conditions
pc.responder = new RelayResponder( this, "causeError_Result", "causeError_Fault" );
function causeError_Result(re:ResultEvent)
{
// Display successful result
messageDisplay.text = re.result;
}
function causeError_Fault(fe:FaultEvent)
{
// Display fault returned from service
trace("Error message from causeError is: " + fe.fault.description);
}
This example displays the trace message from the
of the message that is contained in
in the causeError.cfm page.

Note: When you create a ColdFusion page that communicates with Flash, ensure that the ColdFusion page works before
using it with Flash.
