Details

Note: You do not have to use _fetchRow to read a row if you are using a data form or a data table. Instead, use _getColumnAttribute, _getColumnText, or _getColumnValue. [cautionend]

You cannot call the _fetchRow method until after initial viewer display or until a row has been read in, for example with _lockRow.

The _fetchRow method sets SYSRC for error, note, and warning conditions.
