Thank you Dave; I've been telling myself there *must* be an OGNL
solution for this for so long, but hadn't managed to track it down. It's
the first time I've seen this solution posted, and I definately think
it's worth an entry in the FAQ!

Turns out there's some OGNL magic for doing simple loops (start at 0, go to
n-1), and the significance of it never really struck me until the #this
questions.
<s:iterator value="(10).{ #this }">

</s:iterator>
Aww yeah.

Is there a simple syntax with <s:iterator> or
<s:generator> for displaying a
sequence of integers from 0 to N-1 ?
(The value of N is not known at compile time.)
At the moment, the only way I can think of doing this is
not very appealing:
Within the action, create an ArrayList and populate it with
the sequence of
integers. Then iterate over that list with
<s:iterator>.
Is there an easier way? Something that would not involve
the action?
