RangeSize of a VO Iterator

A Row Iterator is an iterator over a collection of View rows or Entity rows. The RangeSize property does not control the number of rows displayed in a table based on the collection. In fact, an applications table in ADF can actually display as many rows as can fit into the available space physically. The RangeSize controls is the number of 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. Else, a typical setting should be

(tableSize + 1)
