    While calling context.registerNewObject(), a NullPointerException is
    thrown (stack trace below). It looks like some relationship value in my
    object is null that should not be, but what could it be?

    There is indeed one relationship that is null, but it can't be
    otherwise because, if I understand properly, I can't add that object to
    this one yet in any case because this object is not yet part of the
    context.

    Is there a Catch 22 here: I can't set the relationship because the
    object does not yet have a context, but the relationship is manditory
    (non-null) so it has to be set before I register the object.

    java.lang.NullPointerException

    Thank you for your help.
