the class GenericDAO method singleUpdateView.

/* ====================================================================== */
/* ====================================================================== */
/**
 * Try to update the given ModelViewEntity by trying to insert/update on the entities of which the view is composed.
 *
 * Works fine with standard O/R mapped models, but has some restrictions meeting more complicated view entities.
 * <li>A direct link is required, which means that one of the ModelViewLink field entries must have a value found
 * in the given view entity, for each ModelViewLink</li>
 * <li>For now, each member entity is updated iteratively, so if eg. the second member entity fails to update,
 * the first is written although. See code for details. Try to use "clean" views, until code is more robust ...</li>
 * <li>For now, aliased field names in views are not processed correctly, I guess. To be honest, I did not
 * find out how to construct such a view - so view fieldnames must have same named fields in member entities.</li>
 * <li>A new exception, e.g. GenericViewNotUpdatable, should be defined and thrown if the update fails</li>
