Description Seth Fitzsimmons 2004-09-03 15:00:27 UTC 
<c:forEach begin="5" end="1" step="-1" var="x">...</c:forEach> complains about
step being <= 0.

How should countdowns be handled if step cannot be negative?
Comment 1 Kris Schneider 2004-09-03 15:17:40 UTC 
Marked as an enhancement since the JSTL 1.1 Spec. states:

Constraints
- If specified, begin must be >= 0.
- If end is specified and it is less than begin, the loop is simply not executed.
- If specified, step must be >= 1

I've reported this to the 1.2 RI:

https://glassfish.dev.java.net/issues/show_bug.cgi?id=1740

We won't be fixing it unless the spec changes.
