Re: Zope.principalannotation bug report

Thanks for the brilliant answer.   I am now able to display a 
rudimentary zope.container view.

That was indeed the problem.  I was looking in the wrong place.

Of course it still needed the  Grok infrastructure to register the 
utility.  And then to
do the following adaptation.

  return IPrincipalClipboard(principalAnnotations)

But altogether not that difficult.   What is interesting is how much 
easier Grok makes ZTK development.  I highly recommend Grok to all 
concerned.

  Thank you for the pointer.  Lots of great stuff over there.  I will 
take a much closer look.  Although it is not targeted at TTW 
development, it is more for administrative use.

So again thank you for the help.  I was quite stuck, and am now back to 
making progress.
