Hello Amir!

Could you check logs in the console? I think there should be a stacktrace with an exception. If so, could you share the stacktrace?

I’ve tried to reproduce the problem in new project with 1.5.0 and 1.5.1 but without success.

Hello Roman,

Thanks for the reply, unfortunately, i could not reproduce any Stacktrace as it doesn’t print any error/logs in my console, but I manage to work around to solve this but not pretty sure it is a good practise or not.

here are the example/workaround i share with you

Could you please reproduce the problem in a small demo project and share it? The clear Jmix project does not show this exception.

To correctly perform logging out, you should use the following code:

protected void logout() {
    AppUI ui = ((AppUI) component.getUI());
    ui.getApp().logout();
}

AppUI#logout() tries to close all screens, clear settings cache, etc.
