[Zope3-checkins] CVS: Zope3/src/zope/app/interfaces/workflow - stateful.py:1.18

[Stephan Richter]

Update of /cvs-repository/Zope3/src/zope/app/interfaces/workflow
In directory cvs.zope.org:/tmp/cvs-serv10755/src/zope/app/interfaces/workflow

Modified Files:
	stateful.py 
Log Message:
Implemented relevant data for Processes (read workflows). You can specify
a schema which contains the fields that should be available as relevant 
data. Once the schema is set, you are able to specify "get" and "set" 
permissions for each field. That;s it for the setup.

When you then create a Content Object that uses the process definition for
which you declared the schema, you will see that there is a form in the 
'Workflows' tab of this content object that allows you to manipulate the
releavant data.

I also enhanced the XML Import/Export to support relevant data and their 
permissions. 

The easiest way to check all this functionality out is to uncomment the 
include directives in browser/workflow/stateful/configure.zcml and 
workflow/stateful/configure.zcml (both at the end of the file).

This completes my code and status review of the workflow package, which I
think is now ready for the beta.
