It sounds like you are traveling down the exact same path I went down a

use an SQL connection pool. In your model's Settings.config file add the

How many ObjectStore objects do you have living? I believe you are only supposed to have one instance for your entire application. I had a lot of trouble with running out of connections when I first started using MiddleKit, and as I recall I fixed it by making a global MySQLObjectStore instance.
I think this creates another problem. A new connection/cursor is
created for every object that is stored when you call
"store.saveChanges()".
If my mysql max_connections variable is less than the number of
objects I have to commit, I'll get an exception like this:

Actually I think it was a change in the MySQLdb API. I believe that
insert_id() moved from the cursor object to the connection object in the
latest versions.
I've fixed it either by installing an older version of MySQLdb or by

Thanks to all for the discussion about MiddleKit vs ZODB. It was

I have never used an OODB, so I might be wrong, but I have always seen
their weakness to be flexibility. You will get stuck with the objects
you use for a particular application. With a relational DB you can map
the data to any type of object. It is a little more complex because of

This isn't a Python problem -- it's a bug in Webware.
If you put a print statement at the end of UnboundMethodError.py you'll
find that the module actually gets imported multiple times. This
somehow causes a mismatch between the instances and the classes that
triggers the error you're noticing.
