Careful: ${bla} substitution takes place before any javascript is run
(before the __javaScript function is called at all, actually), so this
approach will not work.
I'm not sure how you obtian those values, but maybe you would fare
better by using a PostProcessor in your loop that takes care of the
concatenation while you are still gathering values.
