    Augmenting Validation on Subclassed Custom Forms Link to this post

    I have a cusrtom form, with multiple subclasses forms that I want to augment the Validation porion on the sublcasses, but I'm not sure how to go about it.

    The Custom Form

    class LeadCaptureForm extends Form {
       public function __construct($controller, $name) {

          $fields = new FieldList(
          $actions = new FieldList(
           FormAction::create("leadSubmit")->setTitle($controller->FormButton)->setUseButtonTag(true)->addExtraClass('button red small point-right')
          $validation = new RequiredFields(array('Email'));
          parent::__construct($controller, $name, $fields, $actions, $validation);

    The sublcassed forms look like this

    class MarketForm extends LeadCaptureForm {
       function __construct($controller, $name) {
          parent::__construct($controller, $name);

          $newfields = new CompositeField(
          $this->Fields()->insertBefore($newfields, "main");

    On the MarketForm I'd like to add a few of the LeadCaptureForms to the validation as well as the the fields from MarketForm.
