Umbraco-CMS: Preview mode unable to retrieve other pages from cache
Bug summary
Since Umbraco 7.15.0 we are unable to use the preview function in at least 3 of our websites. While loading the previewed page I try to retrieve other pages using content.AncestorOrSelf() or content.Siblings() and I receive null or unexpected results (see screenshots).
Specifics
- 7.15.0 up to 7.15.3
- The bug disappears when
Umbraco.Preview.Modeis set toLegacy
This is interesting, only previously previewed pages are showing up in the list but the page with ID 1050 should not be a sibling.
Expected result
A webpage that loads in successfully without exceptions.
Actual result
NullReferenceException in the code that runs fine outside the preview mode.
