Sorry, I didn't mean to alarm you, I was just posting in a hurry.  Let 
me try to make up for that.

In Seaside 2.5, the simplest way of replacing a component visually with 
another is using #show:.  This is effectively the same thing as #goto:, 
so your old code would work fine if you did:

WAComponent>>goto: otherComponent
	self show: otherComponent

There is also #show:onAnswer:, which takes a block that will be 
triggered when the other component sends #answer: -

self show: yesNoDialog onAnswer: [:bool | bool ifTrue: [...] ifFalse: 
[...]]

This then gets combined with continuation capture to provide the more 
familar #call:

(self call: yesNoDialog)
	ifTrue: [...]
	ifFalse: [...]
