Saving state when navigating.

Question

Hi!

I happen to have huge problem with navigation. Till now I've been using objects filled with data when navigating between pages ex. Frame->Navigate(TypeName(DetailsView::typeid), TooComplicatedObject); 

Everything was working fine, but now I would like to use Resume event. The problem is that it's crashing the app as the page could not be suspended correctly due to this object passed as navigation parameter. It would't be a problem if the navigation was simple 1->2->3->2->1, then I would store object globally. My problem is that the navigatation can be more complicated ex. 1->3->3->3(...) or 1->2->3->3->3(...) (Each number is the same layout filled with different data). I thought about using navigation cache and then refreshing data when navigating to page(data has to be downloaded from server). But maybe there is some better sollution for such problem?
