grok.Container (which derives from
zope.app.container.btree.BTreeContainer) does something different than
For some reason I had to make the model implement IContained (by
subclassing contained.Contained in this case) to get the __parent__
attribute set correctly. :/
This introduced a delicately balanced equilibrium between grok.Model and
grok.Container that I'm unhappy with because it depends on the order of
the base classes of grok.Model to be able to mix-in models and containers.
We could argue that grok.Container always is a model and should not be
mixed in, or we could try harder to figure out what the BTreeContainer
does different that the dependency on Contained is needed.
