Hi all (yet again ;) ),
I ran into this issue on a project I worked on before, but I ended up
changing the design before  it became a significant issue.  this time
around, i don't see a way by it.

i have a class that derives from Folder (or BTreeContainer, it doesn't
really matter for this).  in configure.zcml, i set it up as follows:
         <content class=".consumer.Consumer">
            <implements
               
interface="zope.app.annotation.interfaces.IAttributeAnnotatable"      
         />
            <require
                permission="zope.ManageContent"
                interface="zope.app.container.interfaces.IReadContainer"
                />
            <require
                permission="zope.ManageContent"
                interface="zope.app.container.interfaces.IWriteContainer"
                />
            <require
                permission="zope.ManageContent"
                interface=".interfaces.consumer.IConsumer"
                />
            <require
                permission="zope.ManageContent"
                set_schema=".interfaces.consumer.IConsumer"
                />
        </content>

this doesn't work.  putting in the third-down require statement breaks
it, throwing me a traceback that says something about protectName. 
i've looked through zope.app.security.protectclass (where protectName
comes from), and i just honestly don't see what the issue is.  i've
even tried it with removing the I{Read/Write}Container bits...  the
only difference between this class and any other just class
MyClass(Persistent) style is just that it happens to be a container.

is there something about Folder or BTreeContainer that invokes a
different kind of security checking than a simple Persistent class
derivative?

the issue is that I want/need to be able to both have the class
contain other persistent objects, while simultaneously have it be able
to have a view on it that allows the update and modification of
certain attributes...  like the following:
consumer.full_name
consumer['preferences'] = Preferences()

there are, obviously, ways around this.  i can redesign the way i'm
attempting to use the object, if necessary.  but it works from the
interactive interpreter, it just fails in the zcml.  and if i leave
out the relevant zcml bit, it just throws me "Unauthorized" errors.

anyone have any ideas?

I've put the traceback below...
