Duplicates shown in user interface.

[stefjoosten]

Consider the following interface specification

INTERFACE StudentScripts FOR Tutor : '_SESSION'[SESSION]#(I[Account]/\submittor~;submittor) cRud
  BOX<SCOLS>
        [ indiener : I/\submittor~;submittor cRud
        , scripts : submittor~ cRud
          BOX<SCOLS>
              [ opdracht  : assignment cRud
              , bestand   : content cRUd
              , ingediend : submitted cRud
              ]
        ]

It produces the following effect:

In field "indiener", it is unexpected to see the same atom 3 times.

Reproducing this bug.

It might be due to the fact that no select DISTINCT is being done, because of optimalisations. In this case, the outer select DISTINCT should be wrapped by the frontend. @Michiel-s , do you agree?

This indeed relates to #486, which is not completely resolved and fully tested (yet).

[hanjoosten]

@stefjoosten I have fixed the related bug of #486. I have made a pull request of that fix. However, since you still promised a reproduction path (see the original post above), could you test that this fix solves your problem?

PR is merged. Issue is solved. @stefjoosten please reopen this issue if your case is not solved.
