Hallo,

da eine Anfrage beim maintainer nach einem Update von PloneBooking für
Plone4 leider ohne Antwort blieb, versuche ich es nun selbst.

Nun scheitere ich an folgendem Traceback:
--------------------------------------------------------------------
 2010-11-14 18:48:12 ERROR Application Could not import Products.PloneBooking
Traceback (most recent call last):
  File "/home/ph/plone/4.0/buildout-cache/eggs/Zope2-2.12.11-py2.6-linux-i686.egg/OFS/Application.py",
line 596, in import_product
    product=__import__(pname, global_dict, global_dict, silly)
  File "/home/ph/plone/4.0/buildout-cache/eggs/Products.PloneBooking-2.2.3-py2.6.egg/Products/PloneBooking/__init__.py",

    from Products.PloneBooking.BookingTool import BookingTool
  File "/home/ph/plone/4.0/buildout-cache/eggs/Products.PloneBooking-2.2.3-py2.6.egg/Products/PloneBooking/BookingTool.py",
line 68, in <module>
    class BookingTool(DateManager, UniqueObject, SimpleItem,
ActionProviderBase):
  File "/home/ph/plone/4.0/buildout-cache/eggs/Products.PloneBooking-2.2.3-py2.6.egg/Products/PloneBooking/BookingTool.py",
line 78, in BookingTool
    __implements__ = (ActionProviderBase.__implements__,
AttributeError: class ActionProviderBase has no attribute '__implements__'
------------------------------------------------------------------

In der Doku zur Produktmigration lese ich, dass statt
'__implements__ ='   nun   'implements()' verwendet wird. mir ist aber
nicht klar, wie ich die folgende Zeile ändern muss:

__implements__ = (ActionProviderBase.__implements__,
SimpleItem.__implements__, )

Für Hilfe dankbar
 Frank
