In my case, I dynamically add/remove/exec rules at run-time. KnowledgeBase instance is constantly updated.
When a rule needs to be added or removed, I do it in temporary KnowledgeBuilder instance. If there are no errors, I update main KnowledgeBase instance using "addKnowledgePackages". I did'nt get any errors ... I do understand that this may be due to KB corruption. I use hasErrors() & getErrors() to check if there are any errors. Do I need to check something else?
