Try using  the following:

 

 dataSource.getUniversalID() 

 Be sure within your data table you are accessing the current row by the collection name (often something like 'rowData'). If a view is the datasource for your data table then each item will be a NotesXspViewEntry which does have the getUniversalID() method so rowData.getUniversalID() should work. Just be sure you're working with the current row, not the datasource itself.
