Hi, This problem needs to be solved conceptually before technically. Assuming (I can't use Agenda Groups in decision tables). SUMMARY ------- Some rules evaluate some logic and pass it to a rule which aggregates the logic to give the final outcome. Now that requires use of update. (or insert) Before I get into the details as I usually do; one quick Question: Q) Are recursion a result of update() or can they be caused by insert()??? because i have an alternative hypothesis using insert() (described in my solution section) DETAILS -------- So exact scenario in 'Rules' is below; and this causes infinite-recursion. Note: I've solved it but I'm looking for something more sophisticated or clean. My current solution is written below after the problem is described in rules. rule "Main" no-loop true when cntct: Contact(initialized==true) eval(cntct.extendedProperty("Table1_Output",true) ==true) then ... end # setExtendedProperty = hashMap rule "Rule_1" no-loop true when cntct: Contact(initialized==true) cfg_tab1: BooleanConfiguration(value!=false, param=="x1") then cntct.setExtendedProperty("Table1_Output", false); ... update(cntct); end rule "Rule_2" no-loop true when cntct: Contact(initialized==true) cfg_tab2: BooleanConfiguration(value!=false, param=="x2") then cntct.setExtendedProperty("Table2_Output", false); ... update(cntct); end rule "Rule_3" no-loop true when cntct: Contact(initialized==true) cfg_tab3: BooleanConfiguration(value!=false, param=="x3") then cntct.setExtendedProperty("Table3_Output", false); ... update(cntct); end ----------------------- My solution: take one of the rules: rule "Rule_3" no-loop true when cntct: Contact(initialized==true) cfg_tab3: BooleanConfiguration(value!=false, param=="x3") ## Line below filters & restrcits the execution to once only per table ## eval(cntct.extendedProperty("Table1_Output",true) ==true) then cntct.setExtendedProperty("Table3_Output", false); ... update(cntct); end Criticism of my own solution: 1. This solution, will only allow one rule to fire per table (For each rule 1, there is a table of rules like rule 1, similarly for rule 2 type rules there is a table if you just play with true and false values in those rules)? Even with Agenda-Groups; again how do you do an update() once you know the rules of the agenda have all fired??? Can we program that in the rules itself?? 2. Can i use insert instead of update(cntct) and insert another Object into working memoy and evaluate that as part of a condition to prevent recursion? I feel adding conditions to control activations and sequence as a path of long term confusion, so can you please provide a more sophisticated approach or re- evaluate my approaches to the least?
