Clicking on reference (i) icon in Service Portal shows error "No elements to display"
Could be one of 2 things:
1 - The default view has a field of type "Field Name". This issue is a PRB that is fixed in Madrid.
2 - There is a corrupted field on the view. In my case, one of the columns in the view had an incorrect value for table reference in the dictionary.
1 - Review the fields in the default view of the table being referenced and make sure there is no field of type "Field Name". If you are already in Madrid, look at solution 2.
2 - Start removing fields from the default view on the affected table until you find the one causing issues, then open the dictionary entry for that column and review its configuration. Open a Case with support if unable to find what is wrong.
