[ https://issues.jboss.org/browse/DROOLS-1247?page=com.atlassian.jira.plugi... ] Mario Fusco commented on DROOLS-1247: ------------------------------------- Partially fixed by https://github.com/droolsjbpm/drools/commit/45fb1d622759d3f439b9a089fa1b5... There is still one unresolved test failure that needs to be investigated and fixed https://github.com/droolsjbpm/drools/commit/45fb1d622759d3f439b9a089fa1b5... The NPE in that test is caused by the fact that the same NotNode is evaluated twice during the same flushing operation and the second time there is a staged child left tuple that it tries to remove. The problem is that the node is not the tip of the segment so there isn't actually any staged list to be cleared and the NPE is thrown when the node tries to do so. The other interesting fact is that the path is already totally linked during that evaluation so it would also important to figure out why the same test doesn't fail in lazy mode. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
