"getItemIndex()" is a method of collections. I'd advise creating a
bindable instance variable typed as a collection (XMLListCollection or
ArrayCollection), and assigning its value in a result handler. Bind the
list to that var. Then you can do:
value="{outerDocument.acData.getItemIndex(data)"

Subject: [flexcoders] Re: itemrenderer dataprovider index?
i've already tried getItemIndex and failed, i suppose that i'm
implementing it wrong. I've attempted a number of times similar to
this attempt:
<mx:List dataprovider="dProvider.incrementalData">
<mx:itemrenderer>
<mx:component>
<p:custom_component dataProvider="{data.element}"
value="{outerDocument.dataModel.dataVal[getItemIndex(this)]}">
</mx:component>
</mx:itemRenderer>
</mx:list>
thie idea is this: as each component in the itemrenderer increments,
it will bind to the dataModel.dataVal[index] to retrieve it's value.
But obviously getItemIndex in this case doesn't work. Any other
ideas? thx in advance -b
