I get this problem too often too, glad to see this is an issue.

So it looks like my problem was Om did not recognize those links as links because ident recognition using mappable-ident? requires that the key is contained in the app state: https://github.com/omcljs/om/blob/master/src/main/om/next.cljc#L2048

my initial app state didn't have those keys at the root - putting dummy values in there fixed that issue for me - maybe that will help you too @hlolli
