[Zope] unpickleerror confusion

[David Bear]

I was going through the example in the Zope Book (new riders) making
slight modifications to the code.  Trying to do the example of using a
post method to create new dtml docs (using python p 84).

Well, after creating the dtml-doc and method, and the python script, and
running it, I get the ugly :

======================================
Zope Error
       Zope has encountered an error while publishing this resource.
       Error Type: UnpickleableError
       Error Value: Cannot pickle objects
Traceback (innermost last):

UnpickleableError: (see above)

=========================

here's the python that is called to save the doc:

========py code============

id='Document_%d' % len(context.objectIds())
context.manage_addProduct['OFSP'].manage_addDTMLDocument(id, title=name, file=abstract)
doc=getattr(context, id)
doc.manage_addProperty('Manager', manager, 'string')
doc.manage_addProperty('StartDate', startDate, 'string')
doc.manage_addProperty('EndDate', endDate, 'string')
doc.manage_addProperty('FundingSourse', fundingSource, 'string')
doc.manage_addProperty('FundingAmount', fundingAmount, 'string')
doc.manage_addProperty('KeyWords', keywords, string)


Any pointers would be greatly appreciated.
