I've reopened bug 789 (http://collector.zope.org/Zope/789) because we observed problems in Zope 2.7.2 with transaction abort by the publisher. The problems can make objects disappear or provoke POSKeyErrors. Florent -- Florent Guillaume, Nuxeo (Paris, France) +33 1 40 33 71 59 http://nuxeo.com mailto:fg at nuxeo.com
