Using a JavaFX Tooltip as form tooltip

[oova]

Can I use a JavaFX Tooltip as form tooltip for my input field? I tried adding it to a TextField via FXML, but the binding via the ID does not seem to work as the tooltip's text was empty (instead of showing the message from the resource bundle). It works fine when I use a Label with the same ID (located underneath the TextField).

Thank you for your support.
