I have inserted your suggested code into my code base and got it working OK. As well as incorporating it into getCount() I have changed getData() so that I can now get the record count and the data with a single query.

There was one rare situation that required a bit of extra coding - it is possible for user A to have a screen with a LAST PAGE option available, but by the time he presses this link user B has deleted one or more records which means that a page with that number no longer exists. If you issue a SELECT with an OFFSET which is out of range then an empty result set is returned, so I have to adjust the OFFSET value and redo the SELECT in order to retrieve the contents of the latest LAST PAGE.

Try the attached file and tell me if it works OK for you as well.
