I will concede that we had discussed an AgendaFilter only recently and a prototype did prove successful. It may not be ideal and based on this thread I'm challenging my team for a pure rule solution. Our specific issue is that the rules need to activate both when a field is tabbed off in a GUI, but also as a result of a higher-level validation of all data within our larger dog show event. In this case, if I added specific logic to the rule, how/when could the rule activate when the overall event is submitted to the session? Perhaps Context( (action == all) || (action == taboff, fieldsAffected contains field1) I viewed the filter as a direct way to allow the activations to be filtered (in the case of taboff, keep only the rules affected by the field) I would welcome any suggestions, I'm still trying to learn as much as I can. Sorry for the smell. -bob _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
