[Zope3-dev] Re: strange behavior of intid-utility

[Tom Gross]

Hi Jürgen,

    thanks for the explanation. But this is not a problem of the 
workflow. It is just a special case of the following situation:

>>> class MyContent(Persistent, Contained):

... 	""" """

>>> class MyContainer(BTreeContainer):

...	def __init__(self):

...		super(MyContainer, self).__init__()

...		self[u'foo'] = MyContent()


which raises a NotYet-exception with IntIds present, but not without. 
And it just uses core zope3 elements. Is this behavior intended?

Cheers
-Tom
