Where does shelve look for unshelved class definitions?

[Stuart Hungerford]

Hi all,

I have a python module foo.py which contains:

class A(object): ...
class B(object): ...

As well as a class that uses shelve (which in turn is
using dumbdbm):

class foo(object): ...
// uses a shelve internally

The methods of foo shelve and restore A and B instances
*but* shelve seems to be looking in the wrong places for
the definitions of A and B when they're "unshelved",
giving the error:

AttributeError: 'module' object has no attribute 'A'

How can I persuade shelve to look in other namespaces for
A and B?

Any advice much appreciated,
Stu

This looks like a problem I had recently. Please take a look at this
news thread:

I hope this link works ;-)
