I'm using Repeater and trying to use its' index to access an
array's data to render folders as panels. I get warnings that I
should be using ArrayCollection (for that folderHeading String I'm
trying to make).
I see that you have Script block within the Repeater block.
That's OK, but it is not doing what you think. The placement of the
Script block does not matter as long as it is good XML. The Flex
compiler just yanks it out of there and puts all of the script code
