I'd also like to hold off on a final release until I can solve my own
problems introduced after B3. I probably won't get to it today,
though.

I hate to be a party pooper, but I have another concern ...
Now that I can insert again (thanks!), I run into this problem. Given:
CollectionElement ->> Item <<- Notification
If I insert an Item (it is just a many-to-many linkage table) in one
request, and then immediately delete it again in the next request, I am
getting optimistic locking exceptions. If I restart the app, I can then
go in and delete it. Here are some of the logs when doing the delete:
item (starting out):
PID=0x00000000000000225c85a35e]{<ObjectId:PSEnumeratedItem,
[EMAIL PROTECTED]>; committed;
[collectionElement=>{<ObjectId:PSLocalCollectionElement,
[EMAIL PROTECTED]>}; moniker=>ES;
notification=>{<ObjectId:FENotification, [EMAIL PROTECTED]>}]}
collectionElement.removeFromItems(item);
[PID=0x00000000000000225c85a35e]{<ObjectId:PSEnumeratedItem,
[EMAIL PROTECTED]>; modified; [collectionElement=>null; moniker=>ES;
notification=>{<ObjectId:FENotification, [EMAIL PROTECTED]>}]}
notification.removeFromItems(item);
[PID=0x00000000000000225c85a35e]{<ObjectId:PSEnumeratedItem,
[EMAIL PROTECTED]>; modified; [collectionElement=>null; moniker=>ES;
notification=>null]}
dataContext.deleteObject(item);
[PID=0x00000000000000225c85a35e]{<ObjectId:PSEnumeratedItem,
[EMAIL PROTECTED]>; deleted; [collectionElement=>null; moniker=>ES;
notification=>null]}
dataContext.commitChanges();
org.objectstyle.cayenne.access.QueryLogger - DELETE FROM PS_Item WHERE
identifier = ? AND elementPID IS NULL AND moniker = ? AND objectPID IS
NULL
org.objectstyle.cayenne.access.QueryLogger - [bind: < 00 00 00 00 00 00

org.objectstyle.cayenne.access.QueryLogger - *** error.
org.objectstyle.cayenne.access.OptimisticLockException: [v.1.2M12 March
23 2006] Optimistic Lock Failure, SQL: [DELETE FROM PS_Item WHERE

Ignore the 1.2M12 -- I'm running against the latest from Subversion
within Eclipse (guess that M12 the last time I did a full build using
ant). The bind output is also misleading -- 4 values for 2 ?'s (I
thought I fixed that at one point, but maybe that was for UPDATE only).
Anyway, this code used to work in 1.2M9 (and earlier). I use optimistic
locking on everything, but there are no cascade/etc delete rules.
I'll experiment/debug more, just thought I'd report it in case you were
trying to put out the release.
Thanks!

Subject: Re: Final release?
Let's at least submit this as a bug. I think I may have an older
Linux box where I can put Sybase and play with a solution that I had
in mind.
In any event whatever fix we end up with, it should be possible to
stick it in a custom PkGenerator, so it shouldn't be a problem for
1.2 users if it goes in release 3.0 (and we can port it to 1.2.1 as
well).
