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.
