I am trying to customize the ESS "Change Office and Communication iView" to hide a couple fields. The way to do this seems to be to go to Content Admin, find the iView to change, Preview it, press CNTR + Right Click the fields in question. Found this solution in posts like: Hide fields in ESS WebDynPro iViews
However, when I preview the Employee Search iView I get the page then I must click on the link "Change Office and Communication data" link which then gives me a 500 Internal Server Error exception "The Web Dynpro Application 'XssMenuArea' has expired. Please restart the application either with the refresh button or click the following link XssMenuArea." So I can't even get to the preview that I need.
