Hello Nitin, If you are required to *redispatch *your *CustomEvent* using * dispatchEvent(event) *in an handler that is handling the *event, *you need to override the *clone()* method.
When the *CustomEvent* is redispatched, the event framework behind the scenes will call the *clone()* method of *CustomEvent* (if overridden) else it will call the *clone()* method of base class *flash.events.**Event.* Now, clone() method of *Event* will return the object of type *Event *instead of *CustomEvent, *which will cause the object to truncate any additional information that was added to *CustomEvent*. Also, the handler for your redispatched event will be expecting an object of type *CustomEvent*, which will now get an object of type *Event *(returned by *clone()* method)*.* This will cause a *Type Coercion Failed* error stating that it cannot convert *flash.events.Event* to your *CustomEvent*type *.* There won't be any runtime error if your handler for redispatched event is expecting an object of *flash.event.Event* type instead of *CustomEvent, *but your additional *CustomEvent* properties will be lost. * * * * Regards Shishir On Fri, Feb 10, 2012 at 12:35 PM, Nitin Gopi <[email protected]> wrote: > Hi All > I am using cairngorm framework in my project.
