> If same records getting prefetched through multiple prefetch paths, the final result will content corrupted records with relationships set to null. Example:
> Paintings are present in one prefetch path:
> SelectQuery q = new SelectQuery(Artist.class);
> q.addPrefetch(Artist.PAINTING_ARRAY_PROPERTY);
> q.addPrefetch(Artist.PAINTING_ARRAY_PROPERTY + "." + Painting.TO_PAINTING_INFO_PROPERTY);
> artist.getPaintingArray().get(0).getPaintingInfo() will contain correct non null PaintingInfo record.
> But if paintings are present in multiple prefetch paths:
> SelectQuery q = new SelectQuery(Artist.class);
> q.addPrefetch(Artist.PAINTING_ARRAY_PROPERTY);
> q.addPrefetch(Artist.PAINTING_ARRAY_PROPERTY + "." + Painting.TO_PAINTING_INFO_PROPERTY);
> q.addPrefetch(Artist.ARTIST_EXHIBIT_ARRAY_PROPERTY);
> q.addPrefetch(Artist.ARTIST_EXHIBIT_ARRAY_PROPERTY + "." + ArtistExhibit.TO_EXHIBIT_PROPERTY);
> q.addPrefetch(Artist.ARTIST_EXHIBIT_ARRAY_PROPERTY + "." + ArtistExhibit.TO_EXHIBIT_PROPERTY + "." + Exhibit.TO_GALLERY_PROPERTY);
> q.addPrefetch(Artist.ARTIST_EXHIBIT_ARRAY_PROPERTY + "." + ArtistExhibit.TO_EXHIBIT_PROPERTY + "." + Exhibit.TO_GALLERY_PROPERTY + "." + Gallery.PAINTING_ARRAY_PROPERTY);
> artist.getPaintingArray().get(0).getPaintingInfo() will return null even if there is PaintingInfo associated with painting.
