[ https://issues.jboss.org/browse/DROOLS-2961?page=com.atlassian.jira.plugi... ] Mark Proctor commented on DROOLS-2961: -------------------------------------- We already have data-driven "when" style execution. If a rule is existence-driven it will need to place all fired activations on a "fired" list. When the group/unit exits everything on the "fired" list needs to go back onto the main agenda list - a sort of "refresh" or "reset" if you like. We can declare a rule as existence-driven or a unit, in which case the whole unit would be existence driven. If a unit is declared data-driven or existence-driven, this is the default for the unit. Any rule can over-ride, so in an existence-driven unit a rule can declare it's data- driven. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
