[Zope3-Users] Zope3 Developers Handbook

Hi Stephan and baldtrol,

I have been working through Stephan's "Zope3 Developers Handbook" and find I
cannot create messages after the Workflow is installed.  My version of Zope
is 3.2 (final) on Windows XP.  Using the debug skin, the error is:

    http://localhost:8080/++skin++Debug/snboard/+/AddMessage.html%3D

    Error type: exceptions.AttributeError | Error object: 'LocalSiteManager'
object has no attribute 'getUtility'

My Traceback is provided below.

I found that baldtrol addressed the same error on the IRC on 21-09-2005 and
suggested a partial fix at
<http://www.zope.org/Members/baldtrol/workflowupdates/file_view>
http://www.zope.org/Members/baldtrol/workflowupdates/file_view

However, baltrol's partial fix seems to create yet a different error:

    Error Type: Exceptions.AttributeError | Error object: 'object' object
has no attribute 'getProcessDefinitionNamesForObject'

Can you please tell me if this Workflow problem has been addressed?

Many thanks,

Stuart
