[Touch-packages] [Bug 1477363] Re: onDestruction is never called in the QML component
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.

[Touch-packages] [Bug 1477363] Re: onDestruction is never called in the QML component
Can you take a look at the code I showed above? it is in the mainview.
Please find the code at:
bzr branch lp:~liu-xiao-guo/debiantrial/ondestruction
On the setting page, it is used as an example for saving the state. If I
understand correctly, it should be called like "Component.onCompleted"
event for each of the component.
Thanks & best regards,
XiaoGuo

Could you be more specific? Like in what context the Page is used? Is it
declared inside a PageStack? or in a separate document? Are you trying
to use it in a PageStack?
