I have a zope product, that uses threads, to control programs running outside zope and doing some async stuff.
What I found is, that i can't do changes from the self-started thread (ChrisW: that's the problem... ;) ).
But how do I get into a transaction do be able to change things on persistent objects? You need a ZODB connection in order to be able to change objects in the ZODB.
You get one (in your new thread!) by from Zope import app root= app() # the ZODB root object but without 'RequestContainer' You can now build a new REQUEST object and use "BaseRequest.traverse" to reach the object you want (identified by an URL). Before you change anything, you need to begin a transaction and finally either commit or abort it. Dieter
