I've already tried suggestion 3, and the index does not seem to bear
any relation to what was clicked. For instance, I can click 3
different things and get back 2, and several other things and get back
4, but never do I get anything other than 2 or 4. I have not even been
able to get the click event to fire on the repeater itself, so it seems
that option 3 is most promising. However, the index valued that is
stored isn't correct.
using
<mx:Repeater id="allBlocks" dataProvider="{contentSource.children()}">
<ac:ContentBlock contentItem="{allBlocks.currentItem}"
rIndex="{allBlocks.currentIndex}" />
</mx:Repeater>
Thanks;
