How i18n the Wicket viewer?

From this thread on the Apache Causeway users mailing list:

I am trying to internationalize the label descriptions of form actions, eg those in ActionParametersFormPanel. Referencing those via their message id inside a .po file didn’t work either. Can this be done?

Yes, it is possible to internationalize both the Wicket viewer’s labels as well as the regular translations of the domain object metadata using the .po translation files as supported by the TranslationService.

Full details of the msgIds that must be added to the translations.po file can be found in i18n section of the beyond the basics guide.
