simulate portal pages in C11.0.7

[ywarmbier]

Hi all,
I try to simulate Portal Pages in C11 which were valid until C10, as it is a showstopper for the migration. More than 2.000 users are used to the easy to use and individual portal pages/dashboards created years ago.
I tried the very good hint from http://queryvision.com/kb/supporting-portal-pages-portal-tabs-ibm-cognos-analytics-11-x and was able to link Reports, e.g.
VALID: <iframe src="https://servername/ibmcognos/bi/?pathRef=.public_folders%2Ffolder1%2Ffolder2%2Freportname&amp;ui_appbar=false&amp;ui_navbar=false&amp;format=HTML&amp;Download=false&amp;prompt=true" width="100%" height="310"></iframe>
Additionally I activated Tabs for the pages. So the look like is pretty well so far

... but... I need your support to link also a folder structure like shown in the queryvision hint. I tried the following but only the standard portal is displayed, as my link is INVALID:

<iframe src="https://servername/ibmcognos/bi/?pathRef=.public_folders%2foldername&amp;b_action=xts.run&amp;m=portal/cc.xts&amp;ui_appbar=false&amp;ui_navbar=false&amp;format=HTML" width="100%" height="310"></iframe>

Thanks
