Themes can be selected using several different rules, in this order:

1. The theme attribute on the specific tag
2. The theme attribute on a tag's surrounding form tag
3. The page-scoped attribute named theme
4. The request-scoped attribute named theme
5. The session-scoped attribute named theme
6. The application-scoped attribute named theme
7. The application.ui.theme property in struts.properties (defaults to xhtml)

Tips

• To override an entire form's theme, just change the theme attribute for the form. (Convenient for using the ajax theme for select forms.)
• To support user-selected "shttp://confluence.twdata.org/pages/editpage.action?pageId=723#
  Wiki Markupkins", override the theme in the user's session.
• To change the theme for the entire application, modify the struts.properties.
