Error Type: AttributeError Error Value: _setId It appears that you ZClass does not include the "standard Python persistent classes". They are required to instantiate the class in the ZODB. You omit it only, when you want your class instances be used for other purposes, e.g. pluggable brains (--> Z SQL methods).
