[Seaside] Magritte Chapter in Seaside Book - Missing Method

[Bruce Prior]

I went back to Seaside2 and tried this:

SystemNavigation new allImplementorsOf: #asComponent

This produced:

an OrderedCollection(

a MethodReference Object >> asComponent
a MethodReference PRCommand >> asComponent
a MethodReference PRViewCommand >> asComponent
a MethodReference WADecoration >> asComponent)

If I try this in Seaside3 there are no such implementors.

How would I modify the example in the Seaside Book where asComponent is 
used?
