+     * before adding it to the profile).

+     * If a control name is specified to the portlet description, returns the defined

+     * <LI>is new portlet instance created everytime someone previews the same portlet?
+     * <LI>should use the same skin as the current pane
+     * <LI>if TitlePortletControl is used, the action icons (max, min, etc) are not functional.
+     * Also, customize icon should not be present.
+     * <LI> interactive portlets (such as DatabaseBrowser) lose functionality (such as sorting
+     * in DatabaseBrowser).
