Issue Type:	Bug
Affects Versions:	17.8.0
Assignee:	Unassigned
Components:	Panels
Created:	08/Mar/26 15:45
Priority:	Major
Reporter:	Anca Luca
Description:	The siblings panel, introduced for ~~XWIKI-12599~~, displays the tree rooted in the current page's "space" (parent in the sense of the DocumentReference sense), which displays the actual children of the current page, not its siblings; actually, it's the siblings of the WebHome page of a page tree, which are actually its children). More specifically, if you do the following: create page A, non terminal as children of page A, create pages B and C, non terminal as well as a child of page B, create page D, non terminal at this point, the pages with the following references should be present on your wiki: A.WebHome, A.B.WebHome, A.C.WebHome, A.B.D.WebHome go to the administration of page A and configure the panel "Sibling pages" to be displayed on the page tree, on the left or right, it doesn't matter navigate to page B Expected result: sibling pages panel should display pages B and C with page B being selected page B should be unfoldable to reveal page D Actual result: sibling pages panel displays page D (the child of B)

Description:

The siblings panel, introduced for XWIKI-12599, displays the tree rooted in the current page's "space" (parent in the sense of the DocumentReference sense), which displays the actual children of the current page, not its siblings; actually, it's the siblings of the WebHome page of a page tree, which are actually its children).

More specifically, if you do the following:
* create page A, non terminal
* as children of page A, create pages B and C, non terminal as well
* as a child of page B, create page D, non terminal
** at this point, the pages with the following references should be present on your wiki: A.WebHome, A.B.WebHome, A.C.WebHome, A.B.D.WebHome
* go to the administration of page A and configure the panel "Sibling pages" to be displayed on the page tree, on the left or right, it doesn't matter
* navigate to page B

Expected result:
* sibling pages panel should display pages B and C ( with page B being selected , optional)
* page B should be unfoldable to reveal page D

Actual result:
* sibling pages panel displays page D (the child of B)

	If, after having done the steps in the description of this ticket, an extra page, E, is created, terminal, as a child of A, and one navigates to page E, the sibling pages panel will indeed display B, C and E.

	If, after having done the steps in the description of this ticket, an extra page, E, is created, _terminal_, as a child of A, and one navigates to page E, the sibling pages panel will indeed display B, C and E. !image-2026-03-08-15-51-25-844.png\|thumbnail!
