14.6.6 Experiencing Validation Failure in UI

Show validation failures in the UI using the same shared business logic your REST APIs use.

After you set up the shared Action Item logic in the ACTION_ITEMS_COMMON package, app pages use it declaratively through Invoke API page processes or validations. The figure below shows what users see when saving an action item team with two leads. In the figure, the user clicked (Apply Changes) on the Action Item edit page for the Website Redesign Project. The Action Team grid below shows both Levi and Opal as having the role of Lead. The error notification area appears with an orange triangle containing an exclamation point and the title "1 error has occurred". The application specific error appears below that as a bulleted message: "Only one Lead per action team".
