[Zope3-checkins] SVN: Zope3/trunk/src/zope/app/uniqueid/browser/ fix registered object view (UniqueIdUtility/@@index.html):

[Dominik Huber]

Log message for revision 28423:
  fix registered object view (UniqueIdUtility/@@index.html):
  - deletion of nested objects is leading 
    to orphan object references (parentless).
  - their contexts and therefore their paths can
    not be evaluated which was leading to an error.
