Subject: RE: [flexcoders] Databinding in component
Yes, when repeater instantiates components, it creates a array
of ids for each specific id, so each mySlider has an id mySlider[n]
where n is the index of the item.
The cleanest way to deal with this is to create a custom
component containing all the components and repeat that component. Pass
in a reference to the entire currentItem into a typed setter function.
You will find that doing this simplifies repeater work
immensely, especially when you need to dispatch an event and access the
dataProvider item in the handler. You will not need getRepeaterItem().

Subject: RE: [flexcoders] Databinding in component
In this test case below, why do I get a warning message for the
mx:Label that databinding may not be able to detect changes in the
HSlider? I'm just trying to create labels that always shows the value
of the respective slider. Since this is in a repeater, is it a conflict
with the way I assign id to the slider? What's the preferred way to do
this?
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml
<http://www.adobe.com/2006/mxml> " layout="absolute"
applicationComplete="init()">
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;
[Bindable]
private var _dp:ArrayCollection = new ArrayCollection();
private function init():void
{
_dp.addItem(1)
_dp.addItem(2)
_dp.addItem(3)
}
]]>
</mx:Script>
<mx:Panel>
<mx:Repeater id="sliderRepeater" dataProvider="{_dp}" >
<mx:VBox>
<mx:HSlider id="mySlider"/>
<mx:Label text="{mySlider.value}"/>
</mx:VBox>
</mx:Repeater>
</mx:Panel>
</mx:Application>
