Hello everybody.
I’m trying to write MVP project using spring boot and vaadin.
I used info from https://www.baeldung.com/spring-boot-vaadin and created GridPresenter and EditPresenter with own views and models.
When I run app all is good. But after refreshing page I got Assertion error: No Child node found with id -1.
I think problem with @UIScope or sth like this.
Can u help me, please?
Are you using Lombok? That might be the source of problems.

yes, but how can getter make a problem?
It’s “magic” dynamically generated code. It wouldn’t be the first time that comes with unintended consequences. Mind you, it’s just my guess.

Deleting Lombok doesn’t help. I’ve tryed to find info about scopes but there is only [https://vaadin.com/docs/v13/flow/spring/tutorial-spring-scopes.html]

this helped me. I had to add @UIScope on View and Presenter.
Bwt is it a good practice to build spring boot app with mvp pattern?

Yes, it’s fine.
Here is some more information about Spring scopes: https://www.tutorialspoint.com/spring/spring_bean_scopes.htm
