[rules-users] nested accessors with Sets

[Edson Tirelli]

    Mark,

    Hmmm, something is going on with mvel integration... bellow must work.
    There are work arounds (like using plain java code, or using multiple
patterns), but I think we need to fix that. Can you please include this info
in the ticket.

    Thanks,

     []s
