[Seaside-dev] hot to not use continuations

[Sebastian Sastre]

thanks Lukas. I'm doing something like this and it works:

handleFiltered: aRequestContext
	"Handle the request inside a transaction and with a retry policy"

	[super handleFiltered: aRequestContext] 
		on: WAResponseNotification
		do:[:n| 
			self halt.
			aRequestContext response] 

but when I set the app to use WAMain it won't halt and it renders a blank page.
Is that expected? 
thanks
sebastian
