[Zope3-dev] Proposed widget/schema work for the Rivah sprint (Thursday and Friday this week)

[Adam Groszer]

Dear Gary,

Maybe not too late, I have here one more thing to look at:

It happened that the szerepek attribute of the object implementing the
ISzemely interface was left by default at a value "None". As I tried
to modify the object with a standard generated editform, the exception
below came. I think None should be considered the same as [].
If we agree on that I would maybe consider that even as a bug.
