[ https://issues.jboss.org/browse/DROOLS-981?page=com.atlassian.jira.plugin... ] bing yang updated DROOLS-981: ----------------------------- Description: this issue is due to[ https://issues.jboss.org/browse/DROOLS-978]. I modified the source(NodeTypeEnums.java:Line 88):add if node is null, then return false. there is no NPE, but I find that the updated rule is not be actived by adding the listener on the session. So, I want to know whether my test case is not correct? or the drools does not support the stateful rule's update? or this is the drools's bug? but If i modify the org.drools.core.reteoo.TimerNode like this: public void setNodePosMaskBit(long segmentPos) { // this.nodePosMaskBit = segmentPos; this.nodePosMaskBit = 1; } then the rule will be actived, but i dont know whether this can cause other questions. Thanks! was: this issue is due to[ https://issues.jboss.org/browse/DROOLS-978].
