You changed under CA PLEX Model configuration the FIELDS language from base for sample to spanish or french, but the literal always displays in base language and not in any other selected language available from the scroll down list. Why?
want to use different languages.
As a workaround, create a new Label with proper translated text within required national languages, and then assigning the same label to Text property of the field.
Solution is planned for an upcoming release (no known date yet).
