The bpmportaldashboard.properties file contains the title and description for the default dashboard and out-of-box widgets. However, you need to localize this file for other languages.
Ensure that the localized entries are copied into all locale specific dashboard properties files for all the locales in which you want to localize.
To refresh properties files without re-starting portal server:
1. From the Business Process Portal Administration tab, click System > Configuration > Portal. The Portal Configuration page is displayed.
