[Zope-dev] ZODB.POSException.ConflictError on attribute assignment

It's only one user and within one request where this is happening.  I'm
using ZEO.  There must be something I fundamentally don't understand
about how I assign an attribute to an object in the ZODB.  If you have
any insight nere, I'd appreciate it.

Best,
Brian
