Hi,<br><br>I&#39;m trying to change the result of a collect operation, is this possible?<br><br>This is my sample rule:<br><br>                                rule &quot;Select the only remaining value for each feature Key&quot;<br>
                                 when<br>                                    # Check all not selected features<br>                                    feature : ExpertFeature(selected==false)<br>                                    # if there is one enable feature select this one<br>
                                    list : ArrayList (size == 1) from collect( ExpertFeature(disabled == false, featureKey==feature.featureKey, selected==false) )  <br>                                 then<br>                                      # this is not working<br>
                                      modify( list ) {setSelected(true);}<br>                                 end<br><br>Thanks<br>Joerg<br>
