In a standard IBO master-detail you don't use parameter assignments - IBO
takes care of these itself in an internal event. But, even if you decided
to do it yourself, IBX-style and not use masterlinking or
masterparamlinking, it wouldn't make any sense to do the parameter
assignments in BeforeOpen. You would do them in the AfterScroll, to ensure
that all the invalidation and revalidation was finished and the new master
parameter(s) were available...
