Rendering empty content is not an exceptional case. There is no standard way to say 'my portlet is empty, dont render me' The solution recommended in the previous email (HideDecorator), in addition to rendering empty content (just render an empty string) should work for you with minimal effort I think we could try to better formalize this use case in the upcoming release
