[ZODB-Dev] Re: KeyError / POSKeyError

[Tim Tisdall]

   It took me all day, but I finally managed to figure out how to do
what you suggested.  Unfortunately, I still get the very same error:
POSKeyError, Error Value: 0x01edf2 .  Just to make sure I did it
right, 0x01edf2 is the OID I should use in your solution, right?
