To Reproduce

1. Login as admin;
2. Create two Data Sources with the same name, as ds_1 (virtual);
3. Create two Data Points, one for each of the Data Source, as dp_1 and dp_2 (binary, no change, start 1);
4. Go to 'Modern Interface'
5. Go to 'Data Sources' -> 'Data Sources' -> Data Sources list;
6. Click on Arrow -> Details of the two Data Sources appear, although the second Data Source does not show a list of points -> error, click should only show details of that Data Source

Solution
This function should locate Data Source after xid, not by name.
