>Summary: bad value at "for $x at $pos in $y order by $z"
Initial Comment:
I've just hit this bug. When I use an order by in conjunction with "at
$pos", the position returned is not in the returned set, but in the
source set.
for $x at $pos in (5,2,1,6,7) order by $x return
<TR><TD>{$pos}</TD><TD>{$x}</TD></TR> &
I was expecting the value for $pos to be incremental from 1 to 5, but it
instead returned the position in the initial set.
I think this is a bug. If not, how do I get the actual position after
the sort?

Hi Daniel,
It's not a bug. Probably, you need something like this:
for $x at $pos in
for $y in (5,2,1,6,7)
order by $y
return $y
return
<TR><TD>{$pos}</TD><TD>{$x}</TD></TR>
