ui:validationError

Indicates that the component has validation errors.

To set a handler for the ui:validationError event, use the onError system attribute on a component that extends ui:input, such as ui:inputNumber.

The following ui:inputNumber component handles an error when the ui:button component is pressed. You can fire and handle these events in a client-side controller.
For more information, see Validating Fields.
