Hi Antonio, thanks for your answer.
I've been trying to avoid using XSP and logic sheets quite successfully sofar, since: a. I don't know Java :-( b. It seems possible to do without them. I think I'll query my database for a random number and just add a prefix instead via XSLT. I also use aggregate a lot.
