[rules-users] Setting object's WRAPPER OBJECTS fields to complex result in RHS

[Edson Tirelli]

   Jojan,

   Yes, as I mentioned, it is a JAVA block. What you can do in java, you can
do in RHS... what you can't do in java, you can't do there.

   Although, we are adding MVEL support to version 4.0, where you can use it
instead of java. MVEL has a lot of syntax simplifications to help with such
cases.
