The Tigris and Jetspeed layout decorators have been modified to more gracefully handle the lack of "Folders and Pages" and "Additional Links" navigational content. These panes will now disappear alltogether instead of remaining on the page if they are empty. Furthermore, the entire navigational column will not appear if no navigational elements are present. This leaves the entire browser window width for the portlets in this case.
As an additional note, the NodeSet implementation has been extended to support the standard Collections isEmpty() method. This means that the various navigation collections accessed via the $site variable in the Velocity templates can be tested for the empty state using this method instead of checking size(). Randy
