    To insert, right click on a collection or an empty single element and
    select insert.

    Using the GUI you can generate the exception by:

    - showing the paintings for an artist
    - inserting a new one and entering the details
    - showing the new painting's gallery, inserting a new record and
    entering the details
    - saving back to the server and closing the diagram
    - running the same query again; the exception hits when you try to view
    the paintings for that artist.
