I'm trying to build application using vaadin's vaadin-app-layout-flow.
here is sample app where I want to create slot-ed parts while using mainlayout which is using app-layout. I want to create some kind of master-detail view so in my UserMasterView i'm trying to set entire component/element as master-content slot with this code getElement().setAttribute("slot", "master-content");.
When I display the view on localhost:9999 which should use mainlayout the content of UserMasterView is not displayed. However when I navigate to localhost:9999/users where mainlayout is not used content of UserMasterView is displayed without problem.
So the question is...is it possible to use slot with app-layout? Or is there any other problem which I don't see?
