Validation Error (Deprecated)

This event is fired when a validation error occurs on an input field. To set a handler for the ui:validationError event, use the onError attribute on a component that extends ui:input, such as ui:inputText and ui:inputNumber.

The following ui:inputNumber component displays an error message when the number entered is less than 10. It displays an alert when the error message is cleared.

Here's the client-side controller that handles the input validation and handling of the validation error.

If you're using this event with a component other than those that extend ui:input, register the event first.
