Hi Joris
I think there is no "good" solution in Velocity. I would do it in a
Java component. If you do not want to write a component you could use
Groovy alternatively. There you have the possibility of while.
If it has to be Velocity you could write a DB query which gets you all
your IssueXYZ documents. From those you can get the highest number and
increment your result.
Hope this helps

One of the use cases I have for my wiki is storing
'issues', where
each issue should have a serial number consisting of year + subsequent
number.
I was thinking about a script like this, but one of the problems is:
there is no 'while' function in Velocity.
How would you create a form for this? Thanks for your ideas!

#set($partID=$partID+1)
#set($issueID=$year"-"$partID)
}
#if(!$xwiki.exists($issueID) && $xwiki.hasAccessLevel('edit',
$context.user, $issueID))
$response.sendRedirect($xwiki.getURL($ID, 'inline',
"template=$template}&parent=$parent"))
## Stop processing, since we already sent a redirect.
