[Zope3-dev] widget question: propertyNames/getValue

[Garrett Smith]

I'm trying to make sense of propertyNames in the widget facility. From
what I can see, propertyNames and getValue can be removed from IWidget
(plus appropriate refactoring of existing code) without loosing
functionality.

1 - Nothing in the core uses propertyNames outside the implementation of
getValue.

2 - getattr can be called on a widget directly if you need to get an
attribute by name.

3 - If propertyNames is used for documenting/listing fields supported by
a widget, there are better ways to do this.
