Hi,
Is it possible to use zope.schema.Tuple (or .List) with plone 3? I'm
trying to write a portlet that effectively has a 'LinesField' (in AT
terms) as one of its attributes. To that end, I have::
class IFeedLinksPortlet(IPortletDataProvider):
"""A portlet listing links to syndication feeds.
"""
tal_lines = schema.List(
title=_(u'Objects to display feeds for.'),
description=_(u"TAL statements referring to objects to display
feeds for."),
required=True,
default=['context',])
However, when I try to add my portlet, I get the traceback pasted below.
Any idea how to get through this?
Thanks,
Tim
