Hi,
we've been using the pager tags for a while on a prototype, and I'd like to
extend them with a "first" and "last" tag. We're also doing queries which bring
back many thousands of results. We'll be tuning our SQL later, but it works
fine. Did you put your results in a session attribute?
Also, I'm sure you can nest tags, but I think they have to be written to allow
the jsp compiler to interpret the body rather than just copy it. I need
desperately to get into writing tags to clean up our pages, and the pager taglib
fiddling might just be the intro I need.
As for putting the index above the results, maybe you could have an empty loop
to count the results, show the index, use the pager properties pagerOffset and
pagerMaxItems to display the just results for the current page in a second loop,
and then have a second index below. It does kind of defeat some of the logic
built into the pager tags, though, and it's a bit inefficient.
It's designed for arbitrary iterations, but it would be nice though to be able
to tell it how many things you're display without having to loop through it all,
but it seems fast enough for now.
Matthew.
