There are two problems: 1) the component the APL creates the default metrics is called in parallel by two changes: body.onChildrenChanged is processed in parallel with d.onDefaultColumnWidthChanged, both call the object creation. This can be filtered out, as done in the attached branch.
2) variant type properties are causing trouble when a string value is added. The property change signal is triggered twice, which - in case of the primaryPageSource - causes the primary page to be loaded twice. Changing the property type to string makes APL to work again. With the previous change applied too. ** Branch linked: lp:~zsombi/ubuntu-ui-toolkit/fixAplHickupQt56 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1585996 Title: UITK gallery: can't open subpages on Qt 5.6 because of TypeError To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-ui-toolkit/+bug/1585996/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
