How did you get the source code for the examples? Pages 12-13 of the "Spec UI Framework" booklet give the code for the methods of class WidgetClassList, and there we find:

WidgetClassList >> whenSelectedItemChanged: aBlock
        list whenSelectedItemChanged: aBlock

This looks very much like the 'when....' methods of all the other subclasses of ComposablePresenter. It should at least do something when activated.

Can you FileOut the entire sample class and attached it?
