I've made a custom form which I want to mail and am using PopulateTemplate to format this mail however I get the following error testing in a wamp environment.:

FATAL ERROR: Object::__call() Method 'populateTemplate' not found in class ''

This is my code and I can't find where I went wrong, I've made a ReceptTemplate.ss in mysite/templates/email:

   function doReceptAanvraagForm($data, $form) {

      $email = new Email(
         $from = $data['email'],
         $to = "mymailadres@gmail.com",
         $subject = "Receptaanvraag"
      );
      $email->ss_template = "ReceptTemplate";
      $templateData = array(
      "Anaam" => $data["Anaam"],
         "Vnaam" => $data["Vnaam"]
      );
      $email->populateTemplate($templateData);
      $email->send();

      // Redirect to a page thanking people for registering
      Director::redirect('uitproberen/');
   }

Hi!
I have the same problem and I change Email with Email_Template but in this way mail don't go to sender..With Email was ok. I have v2.2.2
