Adding RadioMenuItem to ToggleGroup in FXML

Question

Somewhere inside my FXML, I have this:

<fx:define>
  <ToggleGroup fx:id="toggleGroup1"/>  
</fx:define>
<Menu fx:id="toggleMyView" text="%MyView">
  <items>
    <RadioMenuItem text="%hide"
                   selected="true"
                   onAction="#handleLoadComponent"
                   toggleGroup="toggleGroup1"/>`

Somehow I get the error:

Unable to coerce toggleGroup1 to class javafx.scene.control.ToggleGroup

But why?

What I'm trying to do is to create a Menu containing several of RadioMenuItem which are all in the same ToggleGroup. How can I add them to the toggle group in my FXML file?

You have to write

toggleGroup="$toggleGroup1"

It also appears to be *important* that your `` block that defines your `ToggleGroup` be **above** any references to said `ToggleGroup`. – Brad Turek Dec 17 '18 at 19:10

If you are using SceneBuilder then set the field ToggleGroup in properties to the name of the group.
