Warner,
Bug seems to be in the DateFieldHandler.java at
public void setValue(final Object target, final Object value)
throws
java.lang.IllegalStateException {
Date date = null;
if (value == null || value instanceof Date) {
date = (Date) value;
} else {
try {
date = parse(value.toString(), _options);
// -- java.sql.Date?
if (_useSQLDate && date != null) {
date = new java.sql.Date(date.getTime());
}
} catch (java.text.ParseException px) {
// -- invalid dateTime
throw new IllegalStateException(px.getMessage());
}
}
_handler.setValue(target, date);
} // -- setValue
parse() method will throw the Bad Date Exception because it does not know
how to handle custom field, but our Handler knows how to .. so, I guess ..
we should directly delegate the call to _handler.setValue() ..
** Please let me know if its a bug or I am doing something wrong, we are
doing POC with caster but its not going well at all.
