Description:
http://objectstyle.org/cayenne/lists/cayenne-devel/2004/04/0001.html
Some DB engines (notably Oracle) can't tell the difference between NULL and "". Oracle (either at the driver level or at the DB level?) converts empty string to nulls with all the consequwnces (e.g. a DB exception when the column allows no nulls).
This affects Cayenne validation, since in most cases validation should pass when a required field has an empty string value... In all cases except when Oracle is the target database.
