Hi Michael,
What is vanilla DRL? Can you briefly explain about it?
Thanks,
McShiv

hmm.. there is a problem with the action of the 2nd rule, so,
converting
it
to vanilla DRL:
rule "SpeCodeSpeValProdPlan12"
salience 50
when
...
then
if(common.getProd() == "{prodCode1}" || common.getPlan() ==
"{planCode1}"){System.out.println("Error");}
end
That doesn't look quite right - you are doing == on strings - .equals
would
be better). I would try that rule on its own, without a DSL - to see
what
is
causing it. Also - why are you doing the if on the RHS? I would get
rid of
that if at all possible to save confusion later.

Hello,
I've just started integrating MR3 into my project (I've previously
used 3.06). The
drl compiles and everything seems fine, but during
tests the following exception is thrown for time to time:
java.lang.ArrayIndexOutOfBoundsException: 17
at org.drools.util.AbstractHashTable$HashTableIterator.next(
AbstractHashTable.java:250)

This only happens during high load tests.
Can anyone help me?
Thanks
