Hi Chuck,
Thanks for the response. I'm 99.9% sure that I'm locking properly,
and the only EOF commandment I might possibly be breaking is the
one that says:
"Don't change the behavior of methods that EOF uses. For example,
do not override to-many relationships to return a sorted list of
the related objects. Make another method to do this."
I'm not overriding to-many relationship methods, but I do sometimes
override setters. For example, I might override a particular
attribute so that I can make a record of the time that the
attribute was changed. Moreover, there are places that I override
accessors for formatting purposes. An example of this would be
overriding a phoneNumber() method to add formatting to the returned
string, or overriding a setPhoneNumber method so that it strips
formatting off. Are these things problematic?
Thanks,
Mark

Hi all,
I've been seeing a lot of exceptions/warnings in the logs for one
of my applications lately, and all seem to have something to do
with an unexpected snapshot state. I'm not really sure what
causes this, or where to look next. Has anyone seen these before?
The first appears just to be logging from something, and not a
full-blown exception:
DEBUG NSLog - decrementSnapshotCountForGlobalID:
com.webobjects.eoaccess.EODatabase
[EMAIL PROTECTED] -- is unable to
decrement snapshot count for object with global ID
_EOIntegralKeyGlobalID[Media (java.lang.Integer)9755] - count is
already 0 or this snapshot doesn't exist
I'm also getting a lot of these, which seem like they might be
related somehow:
Error: java.lang.IllegalStateException
