Problem: Ordering.orderList and date-values
Hi,
if I use
public static void *orderList*(java.util.List objects,
java.util.List orderings)
from the Ordering-Class for sorting date-values it behaves like a toString()
from the date-values is sorted and so it's a order-by-day and not a
order-by-date.
Is there anything I can do?

This is how I did it: http://tinyurl.com/ymxgls

If you are using Unix, get rpl ...
http://www.laffeycomputer.com/rpl.html
You can use it to replace org.objectstyle.cayenne with
org.apache.cayenne recursively.

I didn't expect toString() to be involved, but it was the easiest way to
explain the sorting result.
Currently I'm working with version 1.2.1 ... the problem is also in 1.1.4
What I'm doing, is sorting a relation-list ... a kind of events of an order.
Converting the Date with SimpleDateFormat("yyyyMMdd") to a comparable String
should be no problem, but I need a hint how I can clue this String to the
List ...
BTW: I'm preparing for Cayenne 2.0.1, but converting all packagenames from
org.objectstyle to org.apache is not really fun ... any hints how this can
be done without too many keyboard-action? (There are about 2000 Classes in
our cayenne based projects)

1 additional information:
The orderList method is call with 2 sort criteria 1. Date, 2. Short

java.lang.Comparable is used to order Date fields. "toString" is not
involved anywhere on Cayenne end. Is there a chance you are
converting the values to Strings yourself before doing the
comparison? And what version of Cayenne is that?
