[rules-users] Problem when using multiple rule files (Drools 5)

Hey, i have a drl file with round about 100 rules. when i run this single file everything fine ! When i splip the file into two files and add them seperate into the ruleBase i get the following Exception during the inserting of the facts: java.lang.NullPointerException at org.drools.base.ClassFieldReader.isNullValue(ClassFieldReader.java:183) at org.drools.base.evaluators.EqualityEvaluatorsDefinition$IntegerEqualEvaluator.evaluate(EqualityEvaluatorsDefinition.java:1482) at org.drools.rule.LiteralRestriction.isAllowed(LiteralRestriction.java:92) at org.drools.rule.OrCompositeRestriction.isAllowed(OrCompositeRestriction.java:25) The code looks like this: RuleBase ruleBase = RuleBaseFactory.newRuleBase(); for (int i = 0; i < rules.length; i++) { Package pkg = getPackage(i); ruleBase.addPackage(pkg); } for (int i = 0; i < facts.length; i++) { Object fact = facts[i]; workingMemory.insert(fact); // <<<<< Exception, when multiple rule files } Any ideas ? -- View this message in context: http://www.nabble.com/Problem-when-using-multiple-rule-files-%28Drools-5%...
