Description
To reproduce:
- Start xwiki hsqldb/jetty
- Create a new wiki and verify it appears in the wiki index
- Delete the descriptor page
- Recreate the page manually by editing its objects and adding an XWikiServerClass xobject (and possible a WikiManagerTemplate class)
- Go to the wiki index and note that the wiki is not listed
In the console I got:
