[Zope] Error with cut and paste

[Jochen Knuth]

Hi,

after some customizing of the KnowledgeKit Product, i can not cut and
paste KnowledegeBaseEntries from one KnowledegeBase to another.
I can copy and paste, delete, rename the KnowledgeBaseEntry.

Any hints?

I use the cvs-version of Zope.

Ciao,
Jochen
