Component / dispatching

Question

Hi
I was wondering if anyone could give me some pointers on a
simple problem I`m muddling through.
It`s basically to do with communication between components
and parent app.
The problem is that there is a varying number of the same
component being added to the app and I can't work out how to target
them. I`m adding them on a button click like this:
var newBox:textItem = new textItem;
someContainer.addChild(newBox);
newBox.addEventListener("login", loginHandler);
The textItem component dispatches an event when it is clicked
var e:LoginEvent = new LoginEvent("login",
this.name,);
dispatchEvent(e);
All the dispatching stuff works fine, i`m sending "this.name"
back in there because in the main app I am trying to find out which
instance of the component is reporting back. I`m sure this isn't
the way!
Anyway, after I`ve got the name of the component as a string,
I can`t work out how to get Flex to use it to target the component
- how do i change it from a string to something I can use as a
component id?
I guess basically the main points are;
1. Do you assign an ID when you addChild()?
2. How would you find the ID of and target dynamically added
components?
Thanks very much for any help at all

Answer 1

extend the LoginEvent class to add new property of type
UIComponent, add this constructor and while construcitng LoginEvent
instance add the referece 'this' reference:
var e:LoginEvent = new LoginEvent("login", this.name,
this);
actually, you can get rid of the second parameter as casting
'this' to type of the component would given you access to all of
its properties including 'name' property.
