Nothing wrong in principle. These problems are hard to diagnose because the call stack doesn't tell you who was about to receive the event.
Go look at your listeners to make sure they are defined with the correct type. Log all events you wrap and dispatch so you can see the name of the event that caused the failure, then see who's listening and what kind of event they expect. ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Dominic Pazula Sent: Wednesday, March 26, 2008 5:23 PM To: [email protected] Subject: [flexcoders] Re: Events and .dispatchEvent(); Hi Alex, Thanks for the reply. I'm trying to figure out which of these two (or maybe both) apply in my case. I have my singleton manager, whose implementation is defined as: public class SASManagerImpl extends EventDispatcher implements ISASManager I have a remote object with a listener defined for the FaultEvent.Fault. That listener function is: private function handleFault(event:FaultEvent):void{ var smf:SASManagerFaultEvent = new SASManagerFaultEvent (faultStr,event.bubbles,event.cancelable,event.fault,event.token,event .message); event.stopPropagation(); this.dispatchEvent(smf); } SASManagerFaultEvent extends FaultEvent and defines a few new constants (around the different remote calls I make). Can you tell what I am doing wrong from this? Also, if there is a good tutorial somewhere on this, please send it along. I have looked, but cannot find anything.
