Comes back 5.3.3 for me:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://

<plist version="1.0">

I've ruled out a couple of more issues. I took out creating EOs
through plain old java introspection (although I assume
EOUtilities.createAndInsertInstance uses introspection to create an
EO if it just has the string, and I'm still using that). Also, I
ruled out that it is the way I'm doing locking with the nested
editing context. I took everything out of session, turned on
autolocking in Project Wonder, and created the nested editing context
at the page level rather than at the session level. I don't do any
explicit locking of anything anywhere, but PWO appears to be handling
that perfectly. However, I'm still getting the exception, and in
fact, I'm getting more of these warnings now before actually throwing
the exception:
DEBUG NSLog - decrementSnapshotCountForGlobalID:
com.webobjects.eoaccess.EODatabase
[EMAIL PROTECTED] -- is unable to decrement
snapshot count for object with global ID _EOIntegralKeyGlobalID
[KitQuantity (java.lang.Integer)1346] - count is already 0 or this
snapshot doesn't exist
This might just be a coincidence though.
I'm interested in the possibility of peer editing contexts mentioned
by Mike and Chuck rather than using nested editing contexts. That's
going to be my next attempt. If the editing context is at the
component level, there shouldn't be a problem if someone leaves the
page with the EOs in the EC in a half-finished state. I can't think
of any other issues. Are there any gotchas there I should be aware
of? I'll post the results as soon as I know them...
