#69 paging/sorting issue... when?

[Pashazadeh]

DisplayTag is a great tag library, we've used it in all
of our projects since we found it!

But there is a lack than many has highlighted before,
there is no good way to do paging and sorting in
business tier,

the team has promised that they will solve this issue...

is there any plan for the next release? when will it be
out?

My team also needs this feature. How I see it to be implemented:

1. From request there should be clean way to get the sorting
   column name (not number, but name, it simplifies the job).
   So somewhere static function String getSortColumn(request,
   String table_id).
   1a. also getPagingStart(request, String table_id),
   getPageLength()
2. property of table: preSorted="true/false". Default:
   false. If false do as it is now. If true - don't sort
   anything in displaytag.

With this there is nice way of fast and optimized way of
displaying huge results:

• on DB layer the sorting is done;
• from DB only the displayed 'paging window' records are
  retrieved.

I strongly vote for this feature to be implemented (in fact
it is rather small change in displaytag).
