Rows and deletion

Hi,

                Since its not posible to get accurate row range list because of ghost rows atm.  What is the best solution to get accurate list without ghosts.  What I am doing is listing objects that has more data in detail.

Regards,
                Ásgeir Halldórsson

I don't think the range ghosts behavior is going away.  Is it possible to buffer results and return them once you've reached the page size?

Thanks for the fast response but that would be quite difficult on paging results,  do you know if there is a fix in the works?

Since its not posible to get accurate row range list because of ghost rows atm.  What is the best solution to get accurate list without ghosts.

Page through all of the rows normally, but skip rows which have zero columns.
