[Checkins] SVN: z3c.zalchemy/branches/engine-metadata/src/z3c/zalchemy/demo/demo_ Fixes for demo_3 and demo_4. All demos working again. The solution was to save the RelationalDC object created during the message object's __init__ and flush the session. I am unsure why the particular changes made to the ZAlchemy API required this change.
