I'm trying to create a document map with the same kind of grouping as in the report book demo: http://demos.telerik.com/reporting/report-book/demo.aspx.
I have three groups, which are shown in the attached groups.png file.
The documentation says "nested groups will create nested nodes in the tree". I've placed bookmarks on every group and on the detail section, but they are shown with no grouping at all. Did I miss something?
