    public class ThemeTag

extends MessageTag

Custom tag to look up a theme message in the scope of this page. Messages are looked up using the ApplicationContext's ThemeSource, and thus should support internationalization.

Regards a HTML escaping setting, either on this tag instance, the page level, or the web.xml level.

If "code" isn't set or cannot be resolved, "text" will be used as default message.
