Custom ESS area not showing

Hi folks,

we have defined / customized an own ESS area and the needed WebDynpro. All together works fine if we call this area page and the corresponded iviews in the navigation bar. But if you choose this area in the ESS are group page - the area and iviews will not be display - the ESS are group page will be displayed again... :-((

What can be the problem ? We checked this with Super Admin Role in the EP (no changes) also we check in HCM with su53 for any authorization errors. But found nothing...

Some Ideas what else we have to check ??

thx
