[drools-user] Composite Object

[Mark Emeny]

Hi,   I am just trying to get to grips with Drools and need a bit of help solving what I think is a simple problem.   I have a class “Party” that features the getter “getName()”. This returns an object of type “PersonName”. This class in turn features a “getFirstName()” getter.   How can I create a rule where the LHS is based on some fact regarding the first name of the party? I have so far only been able to achieve this via an “eval” but I’m sure there must be a way using a conventional field constraint(?)   Many thanks,   Mark Emeny.
