Get iViews from Role

Hi

I want to find out on which page a specific iViews is used, that means, where in the (user specific) navigation the iView will be displayed.

When I traverse the navigation nodes, I get with getName() something like "ROLES://portal_content/folder/page". The problem is, I don't know which iViews lie on that page. How can I get them?

When I find a role (IPortalRole object) in the PCD, I don't know what to do with it - is has no method I can use to get access to its content. Is there any way to do so?

Thank you!
