Ok.. I changed my test code in the liveCallback from that shown above to 
the following and my problems disappeared.. It must be my 
misunderstanding of ST I guess..

liveCallback: [:h | h span id: #cart_contents; with: [self 
renderCartContents: self on: h ]];

I guess it needs to write into a span...
