public interface IValidatorAddListener
Optional interface for validators (IValidator
and IFormValidator
) that can
react when validators are added to a Component
.
Implementation note: currently we keep this case simple, stupid, and non-generic. In future
versions we may revisit this and support removal events (IF removal of validators is
ever allowed, which justifies its own discussion). Also, we may look at whether this is a common
event to support for IBehavior
s as well. This raises additional questions that need to
be answered, hence we'll start by supporting just the use case when validators are added to forms
or form components.

void onAdded(Component component)
Form

use case for implementing this interface is for validators to add behaviors to implement
client-side validation capabilities, e.g. through JavaScript, Ajax or just by adding a simple
attribute modifier that sets a "maxlength" attribute.
component
- a Component
to which the validator was just added
