This will backtrack the instance-variable of components B and C. I
don't think this is what you want.

What you need is to backtrack the references to B and C, in case you
replace those with different components. So in case you reference B
and C from instance-variables in A, then your state method needs to
look like:

     ^ Array with: self

This is exactly the same as it was before with #registerObjectForBacktracking:.
