This is the again regarding the NullPointerException issue. Sorry for resending this message again. But I would really appreciate a response on how this can be resolved. The following is the exception I get while removing a package from the RuleBase. java.lang.NullPointerException at org.drools.reteoo.CompositeObjectSinkAdapter.removeObjectSink(CompositeO bjectSinkAdapter.java:125) at org.drools.reteoo.ObjectSource.removeObjectSink(ObjectSource.java:123) at org.drools.reteoo.ObjectTypeNode.removeObjectSink(ObjectTypeNode.java:29 7) at org.drools.reteoo.ObjectTypeNode.remove(ObjectTypeNode.java:232) at org.drools.reteoo.AlphaNode.remove(AlphaNode.java:187) at org.drools.reteoo.AlphaNode.remove(AlphaNode.java:187) at org.drools.reteoo.BetaNode.remove(BetaNode.java:185) at org.drools.reteoo.BetaNode.remove(BetaNode.java:187) at org.drools.reteoo.RuleTerminalNode.remove(RuleTerminalNode.java:439) at org.drools.reteoo.ReteooBuilder.removeRule(ReteooBuilder.java:135) at org.drools.reteoo.ReteooRuleBase.removeRule(ReteooRuleBase.java:259) at org.drools.common.AbstractRuleBase.removePackage(AbstractRuleBase.java:4 08) .... This exception has been occurring after I recently switched to 4.0 MR3.

This is an urgent issue and if anybody has encountered this problem, can you please let me know how it can be resolved? If I have over 3 packages in the RuleBase and I try to remove one of those packages, then I get a NullPointerException. Thanks. ________________________________ From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Sarika Khamitkar Sent: Wednesday, July 11, 2007 3:34 PM To: rules-users(a)lists.jboss.org Subject: [rules-users] NullPointerException while deleting the rule package Hi, I am trying a remove a rule from the RuleBase using the following syntax and get a NullPointerException: ruleBase.removePackage("rule2392016206"); Before removing the package, I am iterating through all the packages in the ruleBase and I can see this package name in the list. I am not sure why this exception is being thrown then. I am using 4.0 MR3. Has this feature changed since 3.0.6? Thanks.
