Never define control flow in #renderContentOn:, always in callbacks.  
#renderContentOn: needs to be a side-effect free display phase.

The point of WATask and #go is to allow the control flow to start 
before anything has been rendered, ie, to be able to immediately call 
another component without some trigger like the user clicking on a 
link.
