hm, the joys of working with trees. some jcr cms explicitly pack child pages under a specific child to keep page hierarchy and other data separate. but i recommend we do the same here as we did in liip.ch : in the twig template, we check `cmf_is_linkable` to know if the child is actually something to link to. that is a safe thing anyways, we could happen to have a document that has no route document (not with simplecms, but otherwise). can you try that?
