Lifecycle hooks

There are several lifecycle hooks available for you to subscribe to and perform various actions in response to events.

These lifecycle hooks can be defined on the JSF definition as such:

$lifeCycle?: {
  $beforeFormInit?: {
    $eval: string;
  };
  $afterFormInit?: {
    $eval: string;
  };
  $beforeFormDestroy?: {
    $eval: string;
  }
  $afterFormDestroy?: {
    $eval: string;
  },
  $onFormValueChange?: {
    $eval: string;
  },
  $onFormStatusChange?: {
    $eval: string;
  }
};
