Shaun, I figured it out - I was in a rush before and didn't take the time to debug. When the eventHandler function is called I was tracing event.currentTarget.id.
In my case event.currentTarget had no properties. It probably would if it extended the EventDispatcher class. Can you give an example of how this is done? Or provide a link to some tutorials? I've searched online and found a few examples. I think the 3rd example on this blog (http://www.darronschall.com/weblog/archives/000100.cfm <http://www.darronschall.com/weblog/archives/000100.cfm> ) is similar to your approach. Thanks for all your help so far. It really cleared up my confusion on event propagation. --- In [email protected], shaun <[EMAIL PROTECTED]> wrote: > > Hi, > > This is the approach i was trying to explain in the previous email. > It was just so your VO doest have to extend EventDispatcher. > Not sure why your getting an id error though..
