Ok, the customer is always right.
"...which instance of a repeater component was clicked..."
This is not difficult if you repeat a custom component. See snippets below.

Goal: Display a list of items using a complex display for each item, and have
each of those items behave like a menu element and respond to a click anywhere
on the item by running a handler function.
One solution is to use a Repeater with a custom component
In the main app or component, declare the Repeater, and the click handler
function.
<mx:Application ...
<mx:Script><![CDATA[
import MyRepeaterItem;
...
private function onRPItemClick(oEvent:Event):void
{
var xmlItem:XML = XML(oEvent.target);
}//onRPItemClick
]]></mx:Script>
<mx:VBox ...>
<mx:Repeater id="rp" dataProvider="{_xmlData}" ...>
<!-- Note we pass in the entire currentItem, and define a click handler
-->
<MyRepeaterItem xmlItem="{rp.currentItem}"
itemClick="onRPItemClick(event)" .../>
</mx:Repeater
</mx:VBox>
</mx:Application>
And in the component, MyRepeaterItem.mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:HBox mouseChildren="false" buttonMode="true" click="onClick(event)" >
<!-- The metadata tag below allows us to define an itemClick handler in mxml,
as in the code above -->
<mx:Metadata>
[Event(name="itemClick", type="flash.events.Event")]
</mx:Metadata>
<mx:Script><![CDATA[
[Bindable]private var _xmlItem:XML;
/** Setter function */
public function set xmlItem(xml:XML):void
{
_xmlItem = xml;
//do any special, non-bound ui stuff you want
}//set xmlItem
/** Getter function */
public function get xmlItem():XML
{
return _xmlItem;
}//get xmlItem
/** Outer VBox Click handler function */
private function onClick():void
{
dispatchEvent(new Event("itemClick",false); //we do not need/want this
event to bubble
}//onClick
]]></mx:Script>
<!-- Now declare the Item UI -->
<mx:Text id="lbDescription" text="[EMAIL PROTECTED]" width="100%"
height="100%" />
</mx:HBox>

They have requested that I avoid creating an editor for them if at all
possible, since it involves a lot of other things I've found to be
quite problematic in Flex (such as knowing which instance of a repeater
component was clicked).
