Steps to reproduce:
- import small confluence space with three small pages (level 1 page, level 2 page, level 3 page) into XWiki
- after import, the hierarchy is lost and all pages are on the same level
- use nested pages migration tool on imported space
- hierarchy is created correctly, but the pages in the hierarchy are empty
I'll attach the mini-export I used for the test.
For larger spaces this makes the import function unusable because manual reordering of the pages would be too much work.
