I am still using zope.formlib. I guess I found the root of the problem.
All the schema fields are security proxied I guess. Removing the
security proxy from those fields before accessing the field's inbuilt
methods solves the problem. So, my code now looks like this
from zope.security.proxy import removeSecurityProxy
sz = len(removeSecurityProxy(self.context.list_field))
li = removeSecurityProxy(self.context.list_field)
res = li[offset:limit]
I guess this is a cleaner approach.
