    Hello,

    is it a problem for cayenne 1.1.3 to prefetch many-to-many
    relationship-objects?

    I get a ClassCastException when I use this:
    ---------------------------------------------------------------
    ProductMedia:Category is an n:m-relationship:

    SelectQuery query = new SelectQuery(ProductMedia.class, qual);
    query.addPrefetch(ProductMedia.HAS_CATEGORY_PROPERTY);

    But I runs fine by 1:m-relationships:
    ---------------------------------------------------------------
    ProductMedia:ProductMediaJpg is an n:m-relationship

    SelectQuery query = new SelectQuery(ProductMedia.class, qual);
    query.addPrefetch(ProductMedia.HAS_PRODUCT_MEDIA_JPG_PROPERTY);

            

    Thanks for help

    Zvonimir
