Hi,
I have a schema with the List field defined:
from zope.interface import Interface
from zope.schema import List, TextLine
class IMyObject(Interface):
myList = List(title=u'mylist', value_type=TextLine(title=u'item'))
Then I implement this using field property.
Then in constructor I assign a Persistent List to this field.
from zope.schema.fieldproperty import FieldProperty
class MyObject(Persistent, Contained):
myList = FieldProperty(IMyObject['myList'])
def __init__(self):
self.myList = PersistentList()
and I get the following stack trace.
Is it intended behavior that schema.List doesn't accept PersistentList?
How do you work around that? I don't want to abadon field validation using
FieldProperty.

__set__
