openHAB2 and default sitemap: what is expected?

Could someone explain the principles of this default sitemap in OH2 ?
When I open it, I just get the main page with all my defined things. But when I click on one of these thing, I just get an empty page… No access to any items.
What is the expected behaviour ?

This only works if you have disabled the “advanced mode” in the preferences of the paper ui (needs to be deactivated BEFORE adding any Thing).
So you should rather consider it a currently broken functionality, waiting for to be implemented.
