title: Validate JavaFX form only after submission using ValidationSupport
body: <p>I'm trying to validate a javafx form using ValidationSupport, the validation is working, but when I access the form the "errors decorations" are already shown, even before the form is submitted or the textfield is focused.   </p>
  
  <pre><code>ValidationSupport validationSupport = new ValidationSupport();
      validationSupport.registerValidator(textField, Validator.createEmptyValidator("Text is required"));
  </code></pre>
  
  <p>The following image shows an example of the form in its initial state.</p>

  <p>How can I force the decoration to show only after the user submit the form or change the TextField value?</p>
