      • As a user that has been granted with 'delegated access', the first time that the user attempts to access 'Delegated Access' from 'My Workspace'/'Home', he gets an ERROR page
      • Also, as an Admin, when browsing the tool, sometimes you get this NPE in the browser. (I believe this was happening when the cache timed out after 10 minutes of no activity, so someone testing would have to wait 10 minutes with nobody else going to the page)
