    Hi everyone,

    I'd like to write some generic code to replace the set of related
    objects of a DataObject with a different set of objects. But I can't
    figure out how to get the list of the target objects.

    Here's some naiive code to illustrate what I'd like to achieve:

    final List<DataObject> oldObjects = (List<DataObject>)
    object.readProperty(name);

    for (final DataObject targetObj : oldObjects) {
         object.removeToManyTarget(name, targetObj, true);
    }

    for (final DataObject targetObj : newObjects) {
         object.addToManyTarget(name, targetObj, true);
    }

    But apparently object.readProperty(…) doesn't return a list of the
    existing target objects.

    What would be the correct way to do this?

    Thanks a lot in advance!
