    Currently (to the best of my knowledge), cayenne always represents a
    to-many relationship as a java.util.List. However, I was thinking it
    would be nifty if cayenne supported map-representations of to-many
    relationships. For instance, you could model a relationship between
    Users and UserPreferences as a map, and specify the "name" property of
    the UserPreferences table as the map key. Does that make sense? Am I
    the only one who thinks that would be incredibly useful? :) Is something
    like this already planned for 3.0?
    If other people would find it useful, then I'd be happy to submit a
    feature request and also work up a patch.

    Robert
