Summary: Error when publishing a branch to the root of a wiki
Issue Type: cid:jira-generated-image-avatar-e37b81e0-f604-4e97-b32a-b98e361f5dca Bug
Affects Versions: 1.28
Assignee: Unassigned
Components: Publication
Created: 03/Jun/26 16:32
Environment: XWiki 18.3.0
Priority: cid:jira-generated-image-static-major-de74d9b9-28e6-4cfb-ba92-c36d4fb39a5b Major
Reporter: Mathieu Pace
Description:

Reproduction step

  1. Create a book with nested pages, something like:
    • Page1
      • Page1-1
        • Page1-1-1
        • Page1-1-2
      • Page1-2
    • Page2
    • Page3
  2. Create a publication:
    • "Source page" must be a sub-page (for instance Page1-1)
    • "Name of the space": type "test"
    • "Destination": pick "Home" (root of the main wiki)
    • select version, etc
  3. Publish

Result

The publication log stops and displays an error:

class java.lang.ClassCastException: class org.xwiki.model.reference.WikiReference cannot be cast to class org.xwiki.model.reference.SpaceReference (org.xwiki.model.reference.WikiReference and org.xwiki.model.reference.SpaceReference are in unnamed module of loader org.eclipse.jetty.ee.webapp.WebAppClassLoader @11ee02f8)

Workaround

There is no pure workaround for this, but publishing in an already existing space

h1. Workaround

There is no pure workaround for this, but publishing in an already existing space   works. Instead of xwiki:Page1-1 as a root of the published book, it will be xwiki:myPublicationSpace.Page1-1
