The same error happens to me. It´s missing the fieldset tag in this file: /portal-admin.sar/portal-admin.war/WEB-INF/jsf/common/editTheme.xhtml | <h:form id="themeform"> | <fieldset style="border: 1px solid;"> | <legend>Theme properties</legend> | | <table> | ..... | </table> | | </fieldset> | | <br /> | <ui:insert name="form_submit"/> | </pre> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4049177#...
