1. Settings -> Wallpaper 2. choose Hunyango 3. Save 4. Settings -> Wallpaper again 5. choose Haenau ACTUAL: "Apply" button will not get enabled, "OK" button has no effect. Workaround: Change Wallpaper first to a Type other than Haenau or Hunyango and then it works. It seems that Hunyango and Haenau are two instances of a common base type and the dialog does not notice that the instance was switched.
Can confirm this on KDE Neon 5.7.
The apply button actually gets enabled but does nothing.
Git commit 76ac242c37b71b7dcdfaa4f78afd365b43610d6f by Kai Uwe Broulik. Committed on 03/01/2017 at 08:35. Pushed by broulik into branch 'Plasma/5.8'. [Containment Appearance] Make sure to always load a config view If StackView is empty, currentItem will be null and we would break all over the place. This can happen when you have a wallpaper without config, so "sourceFile" would stay empty and thus onSourceFileChanged wouldn't be triggered and we wouldn't load anything into our StackView.
