Ah, that's very nice, thanks! Tried it out and it seems to work for Objects() in the schema. However, for Lists(value_type=Object()), I get permission problems: ForbiddenAttribute: ('__getitem__', [<zbsp.fp.Email object at 0x31eed90>]) This happens whenever I try to access the list in any way (e.g. mylist[0] or for i in mylist...). So it seems, I have to declare permissions for this list - but how? For the generic Python list object? My permissions are declared like this: <class class=".fp.MyObj"> <require permission="zope.View" interface=".interfaces.IMyObj" /> <require permission="zope.ManageContent" set_schema=".interfaces.IMyObj" /> </class> I thought this would suffice?
