Summary: Exception in createinline.vm when creating top-level pages from ajax requests
Issue Type: cid:jira-generated-image-avatar-57278b77-030c-457d-9ad1-556d49fd1cb2 Bug
Affects Versions: 16.4.2
Assignee: Unassigned
Components: Actions, Menu
Created: 27/Sep/24 17:47

Description:

Note : the components in this issue may be incorrect, feel free to put better ones.

 

Steps to reproduce :

  • In a new XWiki 16.4.2, create a sub-wiki, let's call it test
  • In the main wiki, create a new menu containing a link to the (inexisting) page : * [[New page 1>>test:Roadmap.WebHome]]
  • Configure the menu so that it is visible after the page header, on the whole farm
  • In the test sub-wiki, click on the abovementioned link to the Roadmap page

Expected : the creation page modal shows up

Actual : nothing happens, the following error shows up in the footer :

Error number 4001 in 4: Error while evaluating velocity template createinline.vm

Note 1 : if you try to have the same set-up with a link to a page that is not a top-level page (for example, test:Roadmap.Page1.WebHome), the issue doesn't occur.

Note 2 : There is probably an easier way to reproduce this issue, but I'm not completely sure how.

 * Note 1 : * if you try to have the same set-up with a link to a page that is not a top-level page (for example, {{test:Roadmap.Page1.WebHome}}), the issue doesn't occur.
* Note 2 : * There is probably an easier way to reproduce this issue, but I'm not completely sure how.

 By digging a little bit, I found out that the source of the issue could come from https://github.com/xwiki/xwiki-platform/blob/82ba90784232fd5947c70b74bbbcfc67a245aca1/xwiki-platform-core/xwiki-platform-oldcore/src/main/java/com/xpn/xwiki/web/CreateActionRequestHandler.java#L317 ; the spaceReference is then re-used in the velocity template.
