[Zope-dev] CopySupport.py patch

[zope-dev@pi.slcc.edu]

I am creating a product and have a special situation where a certain
object must not be pasted in certain places on the Zope hierarchy.
The CopySource class in OFS/CopySupport.py provides a _notifyOfCopyTo
mechanism but the mechanism isn't fully supported in the CopyContainer
class.  Please use the following patch which corrects the problem.  I
have simply copied the _notifyOfCopyTo call from another part of the
file.  This is derived from the Zope 2.1.1 sources, but hopefully the
development version hasn't changed a lot.
