are you using the PaginatedList interface? If so, it does it all for you, the problem is that when you set the page size you'll want the user defined parameters, sort direction, sort column etc.. to remain the same, in which case you'll have to set them in your paginatedList implementation yourself.
I came across this problem when deleting objects from a list, if the user has 10 objects per page and 11 objects in total they see 2 pages, if they go to page 2 and delete one of the objects the displayTag will remain on page two, hence the user sees an empty list, what should happen is they jump to page onbe, as they now have only ten objects, hence I must set the page number manually to one. Hope that helps, John. Hoying, Ken wrote: > Interestingly, when using external sorting everything seems to work > fine. There is no form object as not form is submitted.
