In your example, the Page is declared as an instance. When you close the application, the elements will be destroyed silently, without having their attached Component.onDestruction called.
When you use a Page declared in the way you reported in a PageStack or AdaptivePageLayout, the Page will not be destroyed by these components as it has not been created by the PageStack/AdaptivePagelayout. So you won't get the onDestruction triggered either. In order to have that coming, you need to declare your page as component and add that to the PageStack/AdaptivePageLayout, or in a separate QML document and use that. ** Changed in: ubuntu-ui-toolkit (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-ui-toolkit in Ubuntu. https://bugs.launchpad.net/bugs/1477363 Title: onDestruction is never called in the QML component Status in ubuntu-ui-toolkit package in Ubuntu: Invalid Bug description: I have created a very simple application, and I want to capture the onDestruction event.
