    null component check in the view -- how does it work?

    Allon Rauer Newbie

      in the dvd store example, i notice that some of the view 'code' checks for null component values (e.g., <f:subview rendered="#{currentUser == null}">).

      however, it looks like the SeamVariableResolver automatically creates a component when resolving a name:
      public Object resolveVariable(FacesContext facesContext, String name) throws EvaluationException
      {
      name = name.replace('$', '.');

      log.debug("resolving name: " + name);
      Object component = Component.getInstance(name, true);

      so how can the component value ever be null?
