Nested layouts and spring boot

Flow
1

Hi,

how is it possible to use nested layouts in a vaadin application with spring boot? I tried https://vaadin.com/tutorials/nested-layouts-in-flow, but it’s only okay if i’m not using spring boot. Even @Route(value = “”, layout = LayoutWithMenuBar.class, absolute = false) doesn’t went. I tried to use @UIScope but no effect.

Thanks in advance,
Peter

Here the code parts:

// MainLayout.java

@Theme(value = Lumo.class, variant = Lumo.LIGHT)
public class MainLayout extends Composite<Div> implements RouterLayout, LocaleChangeObserver  {

	private final Div content = new Div();
//...
        layout.add(content); 
//...
       getContent().add(layout);
//...



// AdministrationMenuLayout.java

@ParentLayout(MainLayout.class)
public class AdministrationMenuLayout extends Composite<Div> implements RouterLayout, LocaleChangeObserver{

	private Div content = new Div();
//...
		VerticalLayout pagecontent = new VerticalLayout(content);
//...
        HorizontalLayout page = new HorizontalLayout(menu, pagecontent);
//...
        getContent().add(page); 
//...


// AdministrationView.java

// Only AdministrationView content in browser:
@ParentLayout(AdministrationMenuLayout.class)
@Route(value = AdministrationView.ROUTE)

// AdministrationView content under AdministrationMenuLayout content (in body?):
@Route(value = AdministrationView.ROUTE, layout = AdministrationMenuLayout.class)

public class AdministrationView extends Composite<Div> {
	public static final String ROUTE = "administration";
