Description
STEPS TO REPRODUCE:
Preconditions: Have a fresh HSQLDB/Jetty XWiki instance available.
- Login as Admin
- Go to Wiki Index
- Create a new subwiki (e.g. 'subwikiglobal') and verify it appears in the Wiki Index
- Delete the new subwiki's descriptor page
- Re-create the page manually (with same name) by adding an XWikiServerClass xobject
- Fill in the information as existed on the old (deleted) descriptor page
- Click 'Save & View' to save the page
- Go to Wiki Index
EXPECTED RESULTS
As the previously deleted descriptor page was re-created, the subwiki (e.g. 'subwikiglobal') appears back in the Wiki Index.
ACTUAL RESULTS
When the re-created descriptor's page is saved, its title changed from
Descriptor of the wiki "subwikiglobal"
(as it was initially) to
Descriptor of the wiki "webhome"
I don't know if that's the reason, but the subwiki 'subwikiglobal' does not appear back in the wiki index.
Moreover, on the new descriptor's page 'Descriptor of the wiki "webhome"', when added a WikiManagerTemplate class, I got the following NPE:
