Glad to hear that. However, I am not set up to do my own drools build
and it looks like the link you sent is for the source. Is there a set of
jars for 4.0.x that I can test from? Here is what I am using now:
antlr-runtime-3.0.jar
core-3.2.3.v_686_R32x.jar
drools-compiler-4.0.4.jar
drools-core-4.0.4.jar
mvel14-1.2.21.jar
xstream-1.2.2.jar
Thanks,
Scott

Scott,
I believe this is fixed already. Can you try it out and let us know?

Sorry, the NPE is in ReteTuple.get(Declaration)

Running Drools 4.0.3, on Win 2k sp4, JDK 1.6.0_03.
I am getting this exception after the debugger shows execution
has gone past the end of the rule. The exception is occurring
in ReteTuple.get(Descriptor). I believe the descriptor
argument is null. Can anyone suggest why this might be
happening and what I can do to avoid it?
Thanks,
Scott
