ADF Iterator's RangeSize Property

RangeSize property does not control the number of rows displayed in a table based on the collection. In fact, the rich table in ADF 11g actually will display as many rows as can fit into the available space physically allocated to the table component, so all the range size controls is the number of AJAX transactions that are required to populate the table as the user scrolls up and down. You can set it to -1 if you want to get all records at once.
