In Seaside 3.1, the following seems to work but I need to verify a bit more. In the meantime, this might help you.

JQGetJson>>json: aBlock
	"Defines a json rendering callback."

	self dataType: 'application/json'.
	self respond: [ :response |
		response
			doNotCache;
			contentType: (WAMimeType applicationJson 
				charset: self requestContext handler charSet);
			nextPutAll: (WAJsonCanvas builder
				render: aBlock)]
