[flexcoders] Data binding inside Repeater?

[gmbroth]

Hi,

I'm having a bit of trouble using the following combination of data binding and 
Repeater and could use some enlightenment:

<mx:ArrayCollection id="fred" > some data here... </mx:ArrayCollection >

<mx:ArrayCollection id="measurements" >
  <mx:Object dataProvider={fred} />
</mx:ArrayCollection>

<mx:Repeater id="measurementRepeater" dataProvider="measurements" >
  <my:Chart dataProvider="{measurementRepeater.currentItem.dataProvider"} />
</mx:Repeater>

The intention is to have my chart bind to 'fred' via the Repeater iteration 
over "measurements", a kind of double-binding, I suppose. My chart component 
does render the initial data in 'fred' but doesn't respond to subsequent 
changes to 'fred', i.e., I'm not getting dynamic binding. But if I change the 
repeater line above to this:

  <my:Chart dataProvider="{fred}" />

then everything works as expected. Is there a way to do in MXML what I'm trying 
to do above?

Thanks, Garry
