[Geoffrey De Smet (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-108?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12774420#comment-12774420 ] 

Geoffrey De Smet commented on DROOLS-108:
-----------------------------------------

I agree with Mario that this is not a Drools bug, as it violates the principle that Drools must be notified of any fact changes.
Based on this revelation, it's a potential issue in OptaPlanner, especially when doing VRP time windows, which I 've described in PLANNER-158.
