Jan Steiné commented on DISPL-440:
----------------------------------
I would like to ask if there are any solutions on this issue, since I have
similar problems with the sorting of partial lists. The sorting link in the
header shows always an ascending order. By changing the url by
hand("dir=desc""), I could see that reverse sorting works. As mentioned above
it never sets automatically to descending sort, if ascending order is used
before. Any help appreciated.

> URL: http://jira.codehaus.org/browse/DISPL-440
> Project: DisplayTag
> Issue Type: Bug
> Affects Versions: 1.1
> Reporter: dfc
>
> I'm having several different problems with trying to get a partial list to be
> shown. (I'm using a partial list because the data list could be very long,
> and I don't want to need to find all of it at once.) The object I'm trying
> to show has, essentially, three fields, an ID, a date, and a title.
> If I don't bother implementing the PaginatedList interface, and just pass
> pageSize (or less) objects in, specifying external sort, partial list, and
> size, I get the correct data displayed, but the table header always says that
> I'm showing records 1 through pageSize (or less, if last page), no matter
> what page I'm actually on.
> I tried to get around this by padding out the List with bogus records. ie: I
> would be getting the first page, so I would actually retrieve those, but just
> have bogus data in the rest of the positions. This would work fine with the
> initial sort, but would only show one page in any other sort (either first or
> last page), and would mostly display one page off. So if I wanted to display
> the second page, it would show in the header that it was displaying, for
> example, the 6th through 10th records, but it would actually show the 11th
> through 15th ones.
> So finally, I tried implementing the PaginatedList interface. This worked
> almost perfectly. It was a bit annoying that the arguments changed, but not
> a big deal. What was more of a problem, however, was that I couldn't reverse
> the sort order. I could change it, but the link for the date column sort was
> always for ascending order. For some reason, it was never for descending.
> So I couldn't even test for reverse sorting.
