A field-validation event is for a column in an application table. During user interaction, a field-validation event occurs whenever: •The user leaves a field based on the column after entering or changing the column value in it, for example, by navigating to a different field in the same or a different record, or by attempting to close the window or page. •The user performs an action implying commit, such as choosing File, Save from the menu. During constraint evaluation, a field-validation event occurs whenever: •A constraint effectively supplies a new or changed value for the column as part of an INSERT or UPDATE manipulation. Field-validation events activate domain constraints.
