i tried the following query:
SELECT Id, (SELECT Name FROM Contacts) FROM Account;
Currently the displayed result is "size of the related Objectlist" + (last list value?) of the requested fields.
Is there a inner / nested Table structure which you could use to display/link to all of the returned relationship objects? I guess passing a comma separated value list would not be difficult to implement, but for many returned values not easy to handle for the user.
