[ZODB-Dev] Writing Persistent Class

[Kenneth Miller]

All,

      Quick question.

      I'm trying to make one of my classes persistent. The class  
itself has only simple attributes of general types like  
int,string,timestamp, no lists etc. It seems to work just fine without  
subclassing Persistent, but causes an error when I do. Do I always  
need to subclass persistent?

There error i receive seems to have a problem with my __eq__ method.

Here's the error I get when I do subclass persistent:

.......No handlers could be found for logger "ZODB.Connection"
