Isn't context already a WOServletContext (which is a subclass of
WOContext)? Can you just do:
WOServletContext wosc = (WOServletContext) context;
When I tried that it throws java.lang.ClassCastException

IPortletContext newFact =
PortletContextFactory.createPortletContext(wosc.httpServletRequest
(), wosc.httpServletResponse());
IPortletContext newFact =
PortletContextFactory.createPortletContext(wosc.httpServletRequest
(), wosc.httpServletResponse());
IPortletRequest newReq = newFact.getRequest();
IPortletUser portletUser = newFact.getUser();
String uName = portletUser.getUserName();
I thought that the context would have a request. Am I wrong? Do I
need to create a request?
