No DefaultViewFactory when not extending AbstractView

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Follow the code examples for the View Module
2. Don't extend AbstractView for any views, simply implement the View interface
3. Get NPE throw at line ViewItem:62

What is the expected output? 
  expected views to navigate (activate)

What do you see instead?
  blows up

What version of the product are you using?
  1.3.5

Please provide any additional information below.
  ViewItem:35:
    if (AbstractView.class.isAssignableFrom((Class<?>) viewId))

  - Above conditional fails causing no factory to be set
  - As a work around: In my Application class, I added "ViewHandler.setDefaultViewFactory(new DefaultViewFactory());"

Assumption 1: I don't have to extend AbstractView
"You can use the AbstractView as a basis for your views or then you can 
directly implement the View interface in any way you like it."

Assumption 2: I don't _need_ to set a ViewFactory 
"By default, the ViewItem gets an implementation of the DefaultViewFactory, 
which calls on the view class's default constructor to instantiate the view 
object."
