The base class, GenericServletPortlet checks for the view page as a 
request attribute:

String reqViewPage = (String) request.getAttribute(PARAM_VIEW_PAGE);

Which doesn't do you any good since attributes are not passed from 
action to render phase.

We could propose changing the GenericServletPortlet to look at a render 
parameter, and then in your action you would call setRenderParameter.

Also take a look at the GenericFrameworkPortlet which nicely abstracts 
the concept of multiple views per portlet.
