Using Error and Warning Messages

When components, pages, and fields are set to deferred mode, FieldEdit PeopleCode errors and warnings do not appear when a user exits a field; they appear after the next application server transmission. Therefore, users might not receive an error message until they enter all of the data and click the Save button.

For FieldEdit error messages running in deferred mode, the system changes the field to red and positions the cursor at the field in error when it displays the message, enabling the user to associate the error message with a specific field. However, for warning messages, the system does not display fields nor reposition the cursor. Consequently, create warning messages that clearly describe to which fields they apply. For example, if a page contains a "Date out of range" warning, users will be confused if multiple date fields appear on the page.
