[ https://issues.jboss.org/browse/JBRULES-3660?page=com.atlassian.jira.plug... ] Kiran Kumar A updated JBRULES-3660: ----------------------------------- Description: I am getting the below exception when creating knowledge base using knowledge agent. The things I have done : I have created a package in Guvnor And uploaded a jar using 'New POJO Model Jar' And declared some of the POJOs as events using 'New declarative MOdel' I added role and timestamp annotations to declare them as events. I wrote CEP rules. The below is the one of the rule. rule 'Rule 1' when $eventA: EventA($eventId:eventId) from enrtry-point "STREAM1" not EventB($eventId == eventId, this after[0s,3m] $eventA) from enrtry-point "STREAM1" then helper.doAction1($eventA); I built package. And downloaded changeset.xml. Copied the changeset to project classpath. I created web application having rule engine as a component. I tried creating knowledge base using knowledge agent. ava.lang.NullPointerException at
