[rules-users] NPE after rule consequence executes

[Scott Reed]

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
