It works out of the box. So in this example: 12 rule "Cheese fa...@{row.rownumber}" 13 when 14 Person(age == @{age}) 15 Cheese(type == "@{type}") 16 then 17 list.add("@{log}"); 18 end
If you provide age=null, line 14 is not included in the rule automatically. -----Ursprüngliche Nachricht----- Von: rules-users-boun...@lists.jboss.org [mailto:rules-users-boun...@lists.jboss.org] Im Auftrag von Pavel Tavoda Gesendet: Freitag, 26.
