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;

Thanks.  I'll see if I can get this to translate to my code.
