Re: [rules-users] Reg. Iterating over a list

Hi Thank you very much I partly succeeded using your suggestion. I particularly did the following: rule "list rule " agenda-group "Group 2" dialect "mvel" no-loop true when P : Project(isDefined(P.seq_B)) s : java.util.ArrayList() from collect ( Integer (!(this > 0 && this < 3)) from P.seq_A) //( Integer (this > 0 && this < 3) from P.seq_A); then System.out.println("Rule satisfied # " + P.seq_A); //modify(P) {seq_B = s}; end However, I would like to do every thing all at once in the LHS, or maybe RHS. This is because I have to work around similar functions like the following: 1) collect from collectionA with a boolean constraint into collectionB 2 ) similarly, collect everything that does not satisfy. Custom evaluators - sounds interesting. Sadly, I did not find it. Would be very much useful if you can share an example.
