Check whether the connection is maintained in a "_v_" attribute (in this case, it is per thread). Otherwise, the connection would need to be maintained in a module global registry indexed with a DA id (e.g. its ZODB path).
This is the deep magic of which my previous note speaks.
Where are these details documented (in general terms, not just about DA's), so that I can figure this out without bugging the list too much?
I don't think there are any comprehensive documentation about writing DA's but '_v_' attributes are *volatile* attributes and they are not persisted, see http://zope.org/Wikis/ZODB/VolatileAttributes. -- Roché Compaan Upfront Systems http://www.upfrontsystems.co.za
