In my AJAX form the user has to do a validation as he needs a code to enter the rest of the form (it has 3 pages or more). I have an handler to validate this and this same handler uses that code to do get a node:

  // ON the handler validate()   $code_valid= $this->sessionManager->get('code_valid');      if (empty($code_valid))   {      $this->handlerProperty = $this->contentService->getContentByCodeAndCurrentNodeId($node_id, $name, $code);      $this->sessionManager->set('code_valid', $this->handlerProperty);   }     // On repository Class   public function getContentByCodeAndCurrentNodeId(int $node_id, string $name, string $code)   {     return $this->entityTypeManager->getStorage('node')       ->loadByProperties([         'type' => 'XXXXX',         'event' => $node_id,         'name' => $name,         'code' => $code,       ]);   }    public function confirmForm(array &$form, FormStateInterface $form_state, WebformSubmissionInterface $webform_submission) {      //If submissions is successful, delete private store      $this->sessionManager->delete('code_valid');   } 

My problem is that there’s no way to $this->sessionManager->delete(‘code_valid’) if the user leaves amidst the form. So I was looking for a way to persist the validation result, without resorting to sessionManager/privatestoremanager.

If you want more context the webform is setup to be used on a specific content type (A). It’s used to create/update/delete another content type (B). It’s a one to many relationship between them so this form will create multiple B dynamically, depending on the form content submitted – it can create up to 5 of B. The first step is a validation/auth to be able to use the "real" form (next steps after first).

Thanks in advance!
