ZODB and Boa

I'll try.

>>> <persistent broken __main__.Calendar instance

As you can see, ZODB tries to instanciate a class Calendar, that is supposed
to be defined in the python file that is executed by the interpreter - thus
resulting in the __name__ == "__main__", and no module-name prefixed to the
class name "Calendar". 

But I doubt that Calendar is defined there, in fact your seconds post code
showed there is only some gui-stuff - instead it will be located in some
module, maybe the "calFrame1" you imported, or in module "code" from your
previous post. I assume the latter for now.

Now when you run the code that first created and stored Calendar objects,
you did run it directly, resulting in the fully qualified classname beeing 

__main__.Calendar 

But now running your app, you want it to be code.Calendar. Unfortunately,
there is no way (or at least not  known to me) to alter the class name
after it has been stored.

So this might help: Delete the ZODB FileStorage, and then rerun your
program. It will work. 

Then look at the module "code". Don't use it as you do now - its generally
not a good idea to let code be executed in a modules rump when its
imported. Instead, rewrite it like this:

class Calendar:
    ....

def init():
    # do the initialization stuff you did before in the rump here

if __name__ == "__main__":
    # if executed directly, reimport ourselves under the desired name, and
then run init
    import code
    code.init()

That should then make things work in both ways.
