I have a trigger that is a datamanager-plugin for a Customizer folder. The trigger listens to ADD events. If the trigger rasies an exception as it is notified that a new DataSkin object is being added beneath the customizer folder, I get a ZODB error: 2000-08-27T09:25:38 ERROR(200) ZODB Couldn't load state for '\000\000\000\000\000\000*\336' Traceback (innermost last): File /usr/local/zope/SiteBox/lib/python/ZODB/Connection.py, line 442, in setstate File /usr/local/zope/SiteBox/lib/python/ZODB/FileStorage.py, line 587, in load (Object: /usr/local/zope/SiteBox/var/Data.fs) File /usr/local/zope/SiteBox/lib/python/ZODB/FileStorage.py, line 563, in _load (Object: /usr/local/zope/SiteBox/var/Data.fs) KeyError: *Þ Sometimes I get slightly different errors, where Zope refuses to commit any more transactions.
