[David Kramer]

 Thanks for the reply.  To be very specific...

I'm trying for any way to achieve this: parentDocument.currentAC (in app)
= presentationsSlidesAC (in component), so the main application.mxml has
the currentAC updated. (Loose, tight, whatever.)

Here's the DropLabel.mxml component code:  

<?xml version="1.0" encoding="utf-8"?>
<mx:Label xmlns:mx="http://www.adobe.com/2006/mxml";
text="{data.pTitle}" 
dragEnter="draggedInto(event)"
dragDrop="testDrop(event)"
click="clickHandler(event)"
width="220" textAlign="left" color="#ffffff"
fontSize="12">

<mx:Metadata>
[Event('presentationSelected')]
</mx:Metadata>

<mx:Script>
<![CDATA[

import mx.collections.ArrayCollection;

import mx.controls.Alert;
import mx.core.DragSource;
import mx.managers.DragManager;
import mx.events.DragEvent;

//import flash.data.SQLResult;
//import flash.filesystem.File;
//import flash.data.SQLStatement;
//import flash.data.SQLConnection;
//import flash.events.SQLEvent;
//import flash.events.SQLErrorEvent;

private function draggedInto(event:DragEvent):void

{
DragManager.acceptDragDrop(this);                    
}


private function testDrop(event:DragEvent):void { if
(event.dragSource.hasFormat("items"))


{               

var itemsArray:Array = event.dragSource.dataForFormat("items") as Array;
// breakpoint, examine itemsArray[0]

//Do sql stuff here, which works fine
Alert.show(itemsArray[0].sTitle + '\nadded to\n' + this.text);

}


}

[Bindable]
private var presentationsSlidesAC:ArrayCollection;

//public var selectedPresentation:Object;


private function clickHandler(event:MouseEvent):void


{   
//Do sql stuff here, works fine (requery via SELECT), the result is in an
arrayCollection called presentationsSlidesAC

//I'm trying to simply get this assignment.
//parentDocument.currentAC = presentationsSlidesAC;

}

  Your e-mail is not very clear. There are many ways to get the array
  collection to update. Anyway, if you are using a drop-in item
  renderer, I suggest that you access the listData property of the
  itemRenderer. listData has a property called "owner". So you could
  have your item renderer dispatch an event using the "owner" property.
  This way, the event will be seen as coming from the list itself. so,
  from inside the item renderer: listData.owner.dispatchEvent(<your
  event>); and attach listeners to the list itself to get notified.
