In py2.3 (at least) functions get a __name__ automatically:
Python 2.3.5 (#2, Mar 29 2005, 15:41:06)
[GCC 3.3.5 (Debian 1:3.3.5-8ubuntu2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

'foo'

The ProductContext is creating the attributes correctly on the Product's
custom FactoryDispatcher class. The correct class is being used, and the
*__roles__ attributes are all present and accounted for when the validate()
is invoked. The problem appears to be that we don't even get up to checking
those attributes. The addValues function has no __roles__ attribute, so we
wander into __roles__ attribute checking on the container and fall about
laughing. So I added __roles__ to addValues:
addValues.__roles__ = ('Manager', )
and now everything works. I even removed the ModuleSecurityInfo declarations,
since they appeared to have no effect at all. There's probably some API for
setting that __roles__ attribute, but I'm stuffed if I can find it.
Thanks for the help Dieter,
Richard

Maybe, you do not honor the following requirement (documented in "App.ProductContext.ProductContext.registerClass"): constructors -- A list of constructor methods A method can me a callable object with a __name__ attribute giving the name the method should have in the product, or the method may be a tuple consisting of a name and a callable object. The method must be picklable. The first method will be used as the initial method called when creating an object. Does your "addValue" have a "__name__" attribute with value "addValue"? If so, you may want to analyse the "FactoryDispatcher" mentioned above. You get it (in an interactive interpreter) via app.manage_addProduct[] In its class, you should find your contructors as well as permission attributes of the form "__roles__".

[Zope] Migration pains going to Zope 2.8
I can't instantiate out Product, which is a bit of a hurdle :)
Our Product's registration looks like this (this function is invoked from the
Product's __init__.py):
def initialize(context):
''' Register the CGPublisher class '''
context.registerClass(
CGPublisher,
permission=Perm.ADD_CGPUBLISHERS,
constructors = (addCGPublisherForm, addCGPublisher, addValues,
getMode),
icon='www/CGPublisher.gif',
visibility='Global',
)
Unfortunately, the addCGPublisherForm template can't access the "addValues"
function. The specific error I get is:
Error Type: Unauthorized
Error Value: The container has no security assertions. Access to 'addValues'
of (App.ProductContext.__FactoryDispatcher__ object at 0xb61d30cc) denied.
I tried adding some module security declarations:
security = ModuleSecurityInfo('Products')
security.declarePublic('CGPublisher')
security = ModuleSecurityInfo('Products.CGPublisher')
security.declarePublic('addValues')
security.declarePublic('getMode')
to the initialize() function, but that didn't change anything. Any
suggestions?
