I think I was misreading the traceback. In stepping through the debugger I was able to determine that the type 'unicode' in the error is referring to description entries several layers up the inheritance tree. I had copy/pasted a lot of this from the specifications document and there are the strange backwards single and double quote characters in the text. The documents were created with Framemaker and then saved to PDF. So once I remove all those characters I can get back to the task at hand. Am I correct in thinking that the above definition of Activity.description will constrain the possible types to the classes implementing IItemStructure or a subclass of it? BTW: The traceback is below. I don't think it would have been possible to find this without stepping through the debugger and watching the stack data.

Re: [Zope3-Users] Cannot install Zope 3.3.0 as a Windows Service
Hi Joe, Plone is based on zope2 (though it uses nowadays a lot of zope3 packages also). On Windows I usually avoid having both Plone/Zope2 and Zope 3. Most probably zope 3 and zope 2 are conflicting in this case due to which you are not able to see from zope.app.winservice.service import Service which is a zope3 class. My usual configuration on Windows is: - Python 2.4 - Python for Windows extensions - Zope 3 - Other Python packages which don't conflict with zope 3.

All of my source files have the unicode declaration:

Do those strings inside the list have to be marked as unicode? for

{})], {})], {})], {})]
After flattening the nested construct and unicode converting the
strings:
[u'include', u'archetype_id/value', u'/disposition\\.v1draft/']
Same problem.
If so; if I remove the unicode declaration will that prevent this error?
Nope!
Now I don't know where to search for the problem.
Any ideas?

Benji may recall answering another problem I had with: zope.interface.exceptions.InvalidInterface: Concrete attribute, Where he said one of the class didn't but should inherit from Field. So, I now have several ancestor classes (all the ones that used to inherit from object) that now inherit from Field. It appears I was careless in making these choices. If TestB inherits from Field and TestA inherits from object (current state) or both inherit from Field the problem appears. If TestB inherits from object and TestA inherits from Field or both inherit from object or you change the name of the TestB.description attribute the error goes away. Now it is probably obvious by now that I have no idea what is going on here so if someone has time to add a little Zen i would appreciate it since it will help me unscrew my inheritance tree. :-) Cheers, Tim --- # descr.py -- test behaviour of the Zope schema when using field names as class attributes. from zope.interface import Interface,implements from zope.schema import Field,Object class ITestA(Interface): one=Field( title=uone, description=uone ) class TestA(object): def __init__(self,num): self.one=num class ITestB(Interface): two=Field( title=utwo, description=utwo ) description=Object( schema=ITestA, title=udescrption, description=udescription ) class TestB(Field): def __init__(self,num,descr): self.two=num self.description=descr def buildit(): a=TestA(1) print a.one b=TestB(2,a) print b.two print b.description if __name__ == __main__: buildit() --- # descr.py -- test behaviour of the Zope schema when using field names as class attributes. from zope.interface import Interface,implements from zope.schema import Field,Object class ITestA(Interface): one=Field( title=uone, description=uone ) class TestA(object): def __init__(self,num): self.one=num class ITestB(Interface): two=Field( title=utwo, description=utwo ) description=Object( schema=ITestA, title=udescrption, description=udescription ) class TestB(Field): def __init__(self,num,descr): self.two=num self.description=descr def buildit(): a=TestA(1) print a.one b=TestB(2,a) print b.two print b.description if __name__ == __main__: buildit() signature.asc Description: This is a digitally signed message part ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Though now that I see it, I notice that it's using the non-existent fieldgroup tag, rather than fieldset. I realise it's mostly used in the test, but you may want to fix that. :-) One other question: I want the Group's to be instantiated and populated at run time. That is, I don't want a class for each one, but rather I want to be able to distribute fields across groups via various adapters looked up by the form. Is this sensible? Should I instantiate Group objects directly and set their fields etc? Or should I do something else?
