I was using omniORB3.0.4 and omniORBpy1.5, which don't match. 3.0.5 and
1.5 work fine. However, now I'm getting this:

Client:

    >>> runSomeTests ()
    Create a StorageObject named 'foo'
    Traceback (most recent call last):
    File "<stdin>", line 1, in ?
    File "client.py", line 53, in runSomeTests
    session.nameStorageObject('foo', foo)
    File "sample_idl.py", line 149, in nameStorageObject
    return _omnipy.invoke(self, "nameStorageObject",
    _0_sample.Session._d_nameStorageObject, args)
    omniORB.CORBA.UNKNOWN: Minor: 0, Completed:
    COMPLETED_MAYBE.

Server:

    blackjesus% python startServer.py 
    Using FileStorage
    Started SampleServer <sample._objref_Server instance at 0x835d2b4>
    IDL:omg.org/PortableServer/ServantLocator:1.0

    omniORB: Caught an unexpected Python exception during up-call.

    File "./Server.py", line 83, in nameStorageObject
    sObj = self._servantHelper.lookupDomainObj(sObj)
    AttributeError: SampleSession instance has no attribute
    '_servantHelper'

I've tried working a bit with the inheritance, but couldn't make it
work. I'm pulling ZCF-0.5 in the meantime to see how it goes.

Yep, he's great.

Okay. What I'm missing are some basic examples of manipulating ZODB
objects over the connection, or I'm plain out of context here :-)

Is there some extra documentation?

Take care,
