Hi Lukas, all, I'm using intensely ajax and figured out a way to mimic 95%
of behavior of call:/answer: mechanism with (yet again) the MVP components
I'm using. I can make a component do something like:

AnyPresenter>>askSomeQuestionAndDo: aBlock
	self prompt: 'Some question..' onAnswer: aBlock

MVPPresenter>>prompt: aString onAnswer: aBlock
	"Makes the prompter to be superposed to 
	the receiver until an user answer is given."

	self superpose: (MVPPrompter new
					model: aString;
					onUnsuperposition: aBlock;
					yourself)	

So when AnyPresenter is updated the prompter is superposed until an answer
is given by the user. (In fact you can superpose any presenter to any
presenter).

It's very new, I made that about 10 days ago but I have no complains.

Of course backtrack does not work with this as any other ajax but at least I
have the feature without relinquishing to intense ajax at a very fair price.

Cheers,

Sebastian
PD: Once inside application I'm not using tasks anymore.
