It is not possible to add properties or arguments to event listener.
The convention in Flex is to add (for non-vis comps) an owner property. Note than in general AC can have multiple listeners which is why it doesn't have one. ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Tracy Spratt Sent: Monday, August 27, 2007 7:01 PM To: [email protected] Subject: RE: [flexcoders] Re: Problem with ArrayCollection inside an Object Maybe event.target.parent; Tracy ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of williamkusumo Sent: Monday, August 27, 2007 8:38 PM To: [email protected] Subject: [flexcoders] Re: Problem with ArrayCollection inside an Object It'd be nice if Flex have the ability to pass in a custom argument when you add an event listener and have that argument be available in the function handler.
