[Attribute] renderedIfEmpty [Type] String [Description] 
Indicates whether this table should be rendered if the underlying DataModel is empty. You could as well use rendered="#{not empty bean.list}", but this one causes the getList method of your model bean beeing called up to five times per request, which is not optimal when the list is backed by a DB table. Using renderedIfEmpty="false" solves this problem, because the MyFaces extended HtmlDataTable automatically caches the DataModel and calles the model getter only once per request. Default: true
