[rules-users] averages on different data types

[Edson Tirelli]

   Chris,

   Remember that accumulate is a scope delimiter, meaning variables bound
inside accumulate are not visible outside of it. The error message you see
is the MVEL way of saying: non-existing variable (I guess you are using mvel
as the dialect for the consequence).

   If you want to know what data objects are being inserted/expired from the
working memory, use a working memory listener.
