Re: [rules-users] NPE after rule consequence executes

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 Edson Tirelli's message received 4/9/2008 11:46 AM: Scott, I believe this is fixed already. Can you try it out and let us know? http://anonsvn.labs.jboss.com/labs/jbossrules/branches/4.0.x/ []s Edson 2008/4/8 Scott Reed <sreed(a)avacoda.com&gt;: > Sorry, the NPE is in ReteTuple.get(Declaration) > > Scott Reed's message received 4/8/2008 7:38 PM: > > > 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.
