mvvmFX: Changing Part of a Scene on Runtime - javafx

Question

I'm building a JavaFX Application with mvvmFX.
I have a scene with two panes. Both panes should include any.fxml . I would like to change the included panes at runtime.
So I've found this solution: JavaFX/SceneBuilder - Changing only PART of a Scene and tried to apply it.
So far, so good. Pane2 is displaying any.fxml, but unfortunately, the controller/viewModel is not getting loaded. At least it seems so, any.fxml contains a label which should get modified by the viewModel.
If O add fx:controller="anyVM" to any.fxml and include it via fx:include source="any.fxml" in pane2.fxml everything is working fine. But it's important for me to change it on runtime.
I would be glad if somebody knows a solution how to achieve this.
This is the View of my Main-Scene:
public class Scene implements FxmlView<SceneVM>, Initializable {
#FXML
private BorderPane pane2;
#InjectViewModel
private SceneVM sceneVM;
#Override
public void initialize(URL url, ResourceBundle resourceBundle) {
FXMLLoader loader = new FXMLLoader(getClass().getResource("any.fxml"));
loader.setController(anyVM.class);
try {
pane2.setCenter(loader.load());
} catch (IOException e) {
e.printStackTrace();
}
}
}
This is pane2 in scene.fxml:
<BorderPane fx:id="pane2" layoutX="846.0" prefHeight="547.0" prefWidth="521.0">
<center> <!--<fx:include source="any.fxml" />-->
</center>
</BorderPane>
This is the ViewModel / Controller
#Singleton
public class anyVM implements ViewModel {
private StringProperty lbl = new SimpleStringProperty("27");
public StringProperty getLbl(){
return basementViewKesselTempLbl;
}
public void setLbl(String message){
lbl.set(message);
}
}

In your example code of initialize you are using FXMLLoader which is part of standard JavaFX. However, to load a mvvmFX View with all setup logic you have to use mvvmFX's FluentViewLoader.
The FluentViewLoader uses FXMLLoader internally but does a whole lot more operations like injecting ViewModels into their Views.
So your code should look like this:
#Override
public void initialize(URL url, ResourceBundle resourceBundle) {
ViewTuple<AnyView, AnyViewModel> viewTuple = FluentViewLoader.fxmlView(AnyView.class).load();
pane2.setCenter(viewTuple.getView());
}
