Feedback from russian user learning CUBA re documentation:
Ability to set unique message for a thrown constraint error in the database - you can find it only in the list of all platform properties. Not obvious at all, and it's unlikely that someone would read through the list of all properties.
Suggestion:
Create separate topic with title like "Handling unique constraint violation exceptions in screens".
Mention mechanism of exception handlers, com.haulmont.cuba.gui.exception.UniqueConstraintViolationHandler, mentioned above application property.
Move info about message localization from app properties section to new section.
