An interesting observation ..
1. Adding content into a container in the constructor does work...
2. Adding a Unique Id Utility will stop it working (NotYet error).
e.g.
class Contained(Persistent):
implements(IContained)
class Container(BTreeContainer):
implements(IContainer)
def __init__(self):
super(Container, self).__init__()
self[u'small'] = Contained()
self[u'medium'] = Contained()
self[u'large'] = Contained()
Should this pattern be considered taboo in z3?
