[Zope] ZODB A storage error occured during transaction abort.

[Dennis Allison]

Dieter,

Your lucid description of the source of the "AttributeError: Surrogate
instance has no attribute '_p_oid'" error in the mailing list
archives explains what's happening, but I am at a loss to identify the
method that registers the surrogate and does not have an _p_oid instance.

My problem is trying to identify the source of the failure.  There are a 
couple of external procedures used in the QLOG method which caused the 
conflict error, but nothing other than vanilla DTML nearby in the log.

Do you have any suggestions for localizing the problem?





This is all running on Zope 2.6.2b3, Python 2.3.1, RH7.3.
