triggering `changed` from a global and from code not working.

[TheColorRed]

Note: I am not sure where the point of failure is here, whether I am doing something wrong, or I am attempting something that isn't supported.

I would like changed to be triggered from the rust code where the callback is within a global. I have tried also calling this from another slint file, but that too doesn't do anything.

What I was expecting is for the event to trigger but it doesn't whether I call it from a .rs file or from another .slint file.

export global AppState {
    callback active-project-changed(int);
    in property <int> active-project: 0;
    changed active-project => {
        debug(active-project);
        active-project-changed(active-project);
    }
}

export component AppWindow inherits Window {
  Button  {
    clicked => { AppState.active-project: 0 }
  }
}

slint::slint! {
  export { AppWindow } from "packages/app/ui/main.slint";
  export { AppState } from "packages/app/ui/app-state.slint";
}
let app = AppWindow::new()?;

let app_state = app.global::<AppState>();

app_state.set_active_project(1);

let app = AppWindow::new()?; let app_state = app.global::();
