[Zope-ZEO] Problem deleting

[Monty Taylor]

Deleting products doesn't seem to work to well. I know that's vague, but
here's a quick run down of what I did...
One ZEO Server on one machine with DCOracleStorage. (Ok, I like to live
on the edge) A client on another. All the products are being loaded when
I start the client instance. I added ZPatterns, LoginManager and
Membership (python and ZClass).
I add a few instances of these. I deleted them. Then, I deleted the
product directories and restarted the client. They all still had entires
in Control Panel, which I deleted (along with the Membership ZClass)
On subsequent startups, I got an error message something like:

2000-09-12T13:39:59 ERROR(200) ZODB Couldn't load state for

Could not load oid , pickled data in traceback info may
contain clues

But I had deleted the PortalMember ZClass. I tried packing the database,
but that didn't help. I would have just lived with the annoying error
message, BUT--
Now I couldn't add a Portal anymore. It gave me errors about
DefaultRoleMappings.

I wiped the ZSS and re-installed it, changing nothing client side and
it's all happy now.  The right products have been installed. Is there
something I'm missing? I'll see if I can do it again, but I can't do
that for another few days.

Thanks.
Monty
