My Example is simple - a preparation action with a single aggregate to show a simple list.  I'm using a Table Widget to show the List.  The output is about 600 line items (Multiple page output).  

The list of records showing per page is less and less until there is only 1 record - then it resets and is able to show the max amount on the indicated page.

you can see the white space getting larger with each page. 

Look at the "Bid Ratio" web block in the oml uploaded.
