Tom, It sounds like you are changing the contents of configArray? The ArrayCollection will not notice if you manipulate the underlying Array after the ArrayCollection has been created. You can either manipulate the ArrayCollection directly, or reset the source property on the ArrayCollection after you have changed the Array. Calling refresh() on the ArrayCollection does not fix the problem.
For example, this works: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute"> <mx:Script> <![CDATA[ [Bindable] protected var a:Array = []; ]]> </mx:Script> <mx:creationComplete> <![CDATA[ a.push({a:"one"}); ac.source = ac.source; // reassign the source property to trigger a reset ]]> </mx:creationComplete> <mx:ArrayCollection id="ac" source="{a}"/> <mx:DataGrid dataProvider="{ac}"/> </mx:Application> -Jonathan http://jonathanbranam.net - Flex 3 Anatomy and Solutions On Thu, Jun 26, 2008 at 10:31 AM, Tom McNeer <[EMAIL PROTECTED]> wrote: > I need to have a repeater iterate over an array, displaying an instance > of a custom component for each iteration. > > However, for testing, I am simply attempting to output a button with a > static label within the repeater. > > Here's the basic code on the repeater: > > > <mx:ArrayCollection id="configAC" source="{estimate.configArray}"/> > <mx:VBox width="100%" id="configDisplay"> > <mx:Repeater dataProvider="{configAC}" id="configRepeater"> > <mx:Button label="D'oh" /> > </mx:Repeater> > </mx:VBox> > > Setting a breakpoint after the array is populated, I can see that: > > a) the original array (estimate.configArray) is populated with a single > member, a custom ActionScript object.
