I am using page tree macro. It is used in the page Technology Space > Knowledge Management System. This page has child pages and so I want to use the page tree macro in this page. But it is not working properly. I am not sure if I am setting the id of the document in the right way. I have set the id as document:xwiki:Technology+Space.Knowledge+Management+System.WebHome. The page does not show any tree at all. It says “No pages found”. How I do actually determine the node id of a page?
