I'm using the grid to display a selection where one of the cells is an
ActionLink that currently passes the entity key for use in a detail screen
for via the context, but I want to be able to pass the entry's list index
instead of the key, to avoid a second iteration through the list (doing a
match on the key equality), ex. To be able to do list.get(n) rather than for
(Iterator iter = list.iterator(); iter.hasnext();){if x.key.equals(y.key)
then ...
I previously had an index on the persisted object the list contains, but
this is messy for inserts / deletes ...
I can work around it but if there was something built-in it would be handy.
Regards,
Jim.

What is it you're trying to accomplish, specifically? Ie, why do you need
the row index when you're not rendering?
