Hi

I am pretty new to the world of AS3.0.I have a problem listening to an event.My problem is as follows i have a main application file from which i m dispatching an event with the following syntax  
Application.application.dispatchEvent(e).I intend to catch this event from an actionscript file using the same syntax  
Application.application.addEventListener(e,eventHa ndler);

But the actionscript file throws null pointer exception on Application.application

Any sugestion will be appreciated

Any chance you could attach your .fla file and/or class files?  
Going to be easier to see what’s happening that way.  
Cheers.
