I am performing an upgrade of Siteminder 12.52 to SSO 12.7. After migrating and upgrading the policy store, we were able to successfully register the adminui to the policy store. After logging into AdminUI, we see most of the objects, but we are unable to click or modify any of the objects. Upon clicking, we get an error... "Java.lang.NullPointerException" and nothing happens. Does this sound like a corrupted database? What steps should I take to troubleshoot and remove this error so that we can manage the objects in the policy store from AdminUI?
