[jira] Resolved: (MYFACES-1278) StateManager throws NullPointerException

["Juergen Melzer (JIRA)" <de...@myfaces.apache.org>]

     [ http://issues.apache.org/jira/browse/MYFACES-1278?page=all ]
     
Juergen Melzer resolved MYFACES-1278:
-------------------------------------

    Resolution: Won't Fix

I had used an own Statemanager to prevent myFaces from loading the view from cache, so I can make a quick deploy of jsp files.

public UIViewRoot restoreView(FacesContext facescontext, String viewId, String renderKitId)
  {
    HttpServletRequest request = (HttpServletRequest) facescontext.getExternalContext().getRequest();
    if (request.getParameterMap().size() == 0)
    {
      return null;
    }
    return super.restoreView(facescontext, viewId, renderKitId);
  }
