The root cause of the problem you see is because the Page itself anchor fills to its parent. This was connected badly, and because of that we have this problem.
A fix would be to have property change for each Page added into the hidden item to unset the anchor.fill of the page and restore it when the parent is changed back. However, this would cause Page width changes as well, which is also bad. Another solution is not to reparent but hide the entire Page from the cold,n, which then would break the eventual bindings applied on the opacity/visible properties... We need to study a solution that would prevent Page size changes while reside in the hidden Item. -- 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/1492343 Title: Pages hidden in an AdpativePageLayout stack have their width changed to zero Status in ubuntu-ui-toolkit package in Ubuntu: Confirmed Bug description: As shown in this example [0], if you select the "Albums for artist" button to push a page onto the stack, you can see in the console that the width of the old component is changed to zero, which causes it then to reflow as the width is increased when it is brought back into view. Instead, the width should not be changed when the page is hidden. 0 - http://pastebin.ubuntu.com/12274053/ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-ui-toolkit/+bug/1492343/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
