Hi, I'm trying to change the result of a collect operation, is this possible? This is my sample rule: rule "Select the only remaining value for each feature Key" when # Check all not selected features feature : ExpertFeature(selected==false) # if there is one enable feature select this one list : ArrayList (size == 1) from collect( ExpertFeature(disabled == false, featureKey==feature.featureKey, selected==false) ) then # this is not working modify( list ) {setSelected(true);} end Thanks Joerg _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

I think that there is a simpler way of picking the single ExpertFeature of some featureKey that is not selected and not disabled. when candidate : ExpertFeature( selected == false, fk : featureKey, disabled == false ) not( ExpertFeature( this != candidate, featureKey == fk, selected == false ) ) then modify( candidate ){ setSelected( true ) } -W 2010/4/20 Jörg Herbst <herbsthannover(a)googlemail.com&gt;: > Hi, > > I'm trying to change the result of a collect operation, is this possible? > > This is my sample rule: > > rule "Select the only remaining value for > each feature Key" > when > # Check all not selected features > feature : ExpertFeature(selected==false) > # if there is one enable feature select > this one > list : ArrayList (size == 1) from > collect( ExpertFeature(disabled == false, featureKey==feature.featureKey, > selected==false) ) > then > # this is not working > modify( list ) {setSelected(true);} > end > > Thanks > Joerg > > _______________________________________________ > rules-users mailing list > rules-users(a)lists.jboss.org > https://lists.jboss.org/mailman/listinfo/rules-users > > _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
