since 6.10.0. Use PaginationService instead.
Where there are a _very_ large number of items to paginate (in othe order of 10,000's), loading them all up in memory from the db and then handing them out to the user in a .subList fashion is not very efficient

In this scenario we only want to use this bean to compute our next and previous indexes.

Hence please use this bean in one of two ways (a) set _items_ on this bean and have the bean slice and dice up the uber collection for you and serve it to you with getPage() OR (b) set the total on this bean _only_ and leave the items _alone_. this is recommended for really large collections where its not ideal to load them all up.
