The simplest way to implement #goto: is probably this:

goto: aController
  delegate contents: aController

I should also point out the methods #willCall and #willAnswer on
WAComponent (actually its superclass, WAController).  By default these
return true.  If you know, however, that your component either never sends
#call: or never sends #answer:, you can override them to return false and
Seaside will make the appropiate optimizations. So that, for example,
making a #call: to a component that has #willAnswer returning false is
effectively a #goto:.
